DEV Community: Alex (The Engineering Bolt) ⚡

🤔 How are you building your personal brand?

Alex (The Engineering Bolt) ⚡ — Sat, 14 Mar 2026 17:33:36 +0000

I've been thinking a lot about this lately. Some people have a full content strategy, scheduling tools, and a weekly rhythm. Others post when inspiration strikes. And plenty of smart people avoid it entirely.

Anonymous Survey 👉 https://forms.gle/Yxth9myeRp5Wy3Gx6

There's no wrong answer — but I'm genuinely curious where you fall.

I want to understand how professionals are really approaching personal branding in 2026:

🔧 What tools are you actually using (vs. what you've tried and dropped)?
⏰ How much time are you investing per week?
💰 Are you spending money on it — or going DIY?
🚧 What's the biggest thing holding you back?

I'll put together a write-up of what I find and share it here — figured we could all learn something from how others are approaching this.

Here's what I suspect:
✅ Consistency beats perfection
✅ Most tools get abandoned within 3 months
✅ "I don't have time" usually means "I'm not sure it's worth it"

The FAANG is dead💀

Alex (The Engineering Bolt) ⚡ — Fri, 09 Jan 2026 19:30:43 +0000

Remember when landing a job at Facebook, Amazon, Apple, Netflix, or Google meant you'd made it? When FAANG was the career destination, the undisputed kings of tech?

Those days feel like a lifetime ago.

The acronym itself is showing its age. Facebook rebranded to Meta three years ago, betting the company on a metaverse that never quite materialized. Netflix went from disrupting television to being disrupted, facing fierce competition from every entertainment conglomerate with a streaming app. And the others? They're still massive, still profitable, but the mystique has faded.

Meanwhile, the new power players don't fit neatly into a catchy acronym. OpenAI is reshaping how we think about technology itself. Nvidia's market cap has exploded past most FAANG members. Anthropic, xAI, and a dozen other AI startups are attracting the talent that once flocked exclusively to Silicon Valley's established giants.

The mass layoffs didn't help either. Tens of thousands of engineers who thought they had job security discovered that even FAANG bleeds. The promise of stability evaporated, and with it, part of the allure.

But here's the question: Is FAANG actually dead, or has it just evolved into something different? Are we witnessing the end of an era, or just the tech industry doing what it does best—constantly reinventing itself?

What do you think? Is FAANG still the gold standard, or are we living in a post-FAANG world?

💡Only 20% of Developers are Happy at Work?

Alex (The Engineering Bolt) ⚡ — Wed, 20 Nov 2024 17:03:23 +0000

Within Meta, we conduct a bi-annual survey called Pulse. It's our internal tool for gathering employee feedback about their experiences, focusing on three key dimensions: Manager, Company, and Personal Experience. The survey helps us measure employee and developer happiness, signal team health, and guide our leaders in improving Meta's work environment.

The recently released Stack Overflow 2024 Developer Survey provides a fascinating broader perspective that complements our internal insights. Let's break down the key findings that every tech leader and engineer should know.

Several factors contribute to this widespread unhappiness:

Technical Debt: 62% of developers cite technical debt as a primary source of frustration, indicating that working with outdated or inefficient codebases hampers their productivity and morale. [Stack Overflow Blog]
Salary Declines: Many developers have experienced salary reductions over the past year. For instance, the median salary for PHP developers has decreased to $49,000 annually, reflecting broader economic challenges within the tech industry. [Shift Magazine]
Workplace Pressures: High-pressure environments, characterized by tight deadlines and excessive workloads, contribute to burnout and job dissatisfaction among developers. [Shift Magazine]

47.7% are Complacent
33% are Unhappy

People Managers

25.9% are Happy at Work
47.8% are Complacent
26.3% are Unhappy

Across both groups, complacency is alarmingly high, and genuine job satisfaction remains rare. Although people managers report slightly higher happiness levels, these figures reveal systemic workplace culture, expectations, and support issues.

What factors contribute to this dissatisfaction?

📌 Technical debt and outdated processes

📌 Burnout from high-pressure environments

📌 Limited career growth or unclear advancement paths

📌 Misalignment between developers' values and organizational goals

📊 Top Industries by Developer Employment

Second-highest factor: "Learning/using new tech" scores 17.8 group mean and 18.8 total mean satisfaction.
Building environments/architecture ranks third, at 16.5 (group) and 16.3 (total).
Driving strategy for my team scores 15.7 (group) and 14.1 (total).
Lowest factors: "Securing data," "Observability," and "Open Source" remain under 5 points, showing limited impact on satisfaction.

Unhappy points

Improving quality of code and developer environments is also the top factor for dissatisfied developers, scoring 21.3 (group mean) and 21.1 (total)---highlighting its universal importance.
Learning/using new tech is next, with 19.4 (group) and 18.8 (total).
Building environments/architecture maintains relevance at 16 (group) and 16.3 (total).
Driving strategy for my team is less prioritized among unhappy developers (12.7 group mean), while other areas like "being a power user" and "working with new hardware" score higher.

Key Takeaways

📌 Universal importance: Both happy and unhappy developers strongly prioritize "Improving code quality" and "Learning new tech."

📌 Role-specific differences: Happy developers score "Driving strategy for my team" higher than unhappy ones, indicating this factor's unique motivational impact.

📌 Underestimated factors: Contributions to open source and securing environments, while less impactful overall, might serve as niche drivers for specific developer groups.

📌 Strategic alignment: Opportunities to improve code and explore new technology are vital to boosting satisfaction universally.

The Role of Salary in Satisfaction

Salary remains critical in job satisfaction, but its impact varies significantly by country and context. As Erin Yepis from the Stack Overflow team explained in the "Dev Interrupted" podcast:

"I looked at the top 10 countries that responded to the developer survey. Most happy developers are definitely above the 50th salary percentile, but the relationship between salary and satisfaction is stronger in some countries than others. For example, job satisfaction scores stayed consistent in the Netherlands regardless of salary. However, developers in Brazil or France were more swayed by higher salaries." -- Erin Yepis

This highlights how context matters. Developers' satisfaction may be less tied to income in countries with more robust social safety nets or more balanced work cultures.

Why Satisfaction Matters for Leaders

As a leader, these insights hit home. Whether you're managing a team of engineers or leading at the senior leadership (CxO, VP) level, this data is a call to action:

Invest in your team's growth: Developers value learning opportunities and using new technology. Providing these opportunities keeps teams engaged and excited.
Focus on impact: Improving code quality and enabling developers to build meaningful solutions drives satisfaction at all levels.
Recognize role-specific motivations: Engineering Managers derive joy from driving strategy, while embedded developers thrive on high-quality hardware. Understanding these nuances helps create tailored environments for success.
Foster flexibility: Post-COVID, flexibility remains more important than ever. Hybrid and remote working options consistently rank as top motivators, even above salary in many cases.

What Does It Take to Build High-Performing Teams?

Alex (The Engineering Bolt) ⚡ — Wed, 16 Oct 2024 21:27:03 +0000

Some might say the key to building high-performing teams lies in setting SMART goals, establishing a clear vision, and crafting a multi-year strategy. Others might argue it’s about defining the right team charter, establishing stretch goals, or providing continuous feedback and development opportunities to push people forward. While these are undoubtedly essential elements, they are not the core of what truly makes a team excel.

The reality is much simpler. What we truly need are two things: Integrity and Being Human.

Let me tell you a story.

When I worked for a small startup called DueDil, we faced a significant challenge: building and deploying a new API for all our customers, who were financial institutions with large and complex businesses. This multi-half program required careful planning, execution, migration, and deployment plans to avoid production incidents for our customers.

Our team was small—just four software engineers. But what we lacked in numbers, we made up for in trust and dedication. On deployment day, we were ready with plans A, B, and even C. We had rollback strategies, deployment strategies, and metrics in place. This wasn’t just a team; it was a dream team. It also proved that you don’t need 20 people to create a real business and customer impact. What you need is trust.

As we reached the culmination moment and pressed the button to switch all customers to the new system, we kept our eyes glued to the dashboards. As with any major production deployment, we hit a snag. Problems started unravelling quickly, but our meticulous planning paid off. We managed to get the situation under control by rolling back one of the batches, patching the Redis issues, and continuing forward with the rest of the release.

In hindsight, it was a slight hiccup with no real impact. We handled the situation well, and by the end of the day, all customers were on the new API—more scalable, more performant, and a significant win for the business. This API became one of the core products, generating 40% of the company’s global revenue.

But what made this experience truly special wasn’t just the technical success — the people sitting together and sticking through this process. We had a clear execution plan, knew our roles and responsibilities, and were selfless. We were united in our goal to do good, deliver, and create value, not for ourselves but for others.

Once all was done, one team member took out a guitar, another produced a bottle of wine, and we celebrated. It was a moment of reflection that felt special, bringing us closer together.

This story illustrates the power of Integrity and Being Human in building high-performing teams.

In our case, integrity meant staying true to our commitment to deliver a quality product, even when faced with challenges. It meant being honest about our problems and working together to solve them. Integrity in a team setting looks like this:

Transparent communication, even when things go wrong
Consistency between words and actions
Accountability at all levels
Ethical decision-making, prioritizing long-term success over quick fixes

When team members operate with integrity, it creates a foundation of trust that allows for more open collaboration, innovative problem-solving, and resilience in the face of challenges.

Creating Trust: The Heart of Connection

Our celebration after the deployment wasn’t just about the technical win and recognizing our shared trust. Creating trust in a team means:

Acknowledging that we’re more than just our roles or job titles
Celebrating successes together
Supporting each other through challenges
Recognizing individual contributions and strengths
Creating space for personal connections beyond work

When team members feel seen and valued as whole people, they’re more likely to bring their full selves to work, leading to increased creativity, engagement, and commitment to shared goals.

The Synergy of Integrity and Trust

When integrity and humanity are combined, you create an environment where people feel safe taking risks, sharing ideas, and collaborating openly. High performance becomes a natural outcome rather than a forced goal.

In this atmosphere:

Conflicts are addressed constructively because there’s mutual respect and trust.
Innovation thrives as people feel comfortable sharing unconventional ideas without fear of ridicule or rejection.
Resilience increases because the team supports each other through challenges, knowing they have a safety net of understanding and respect.
Retention improves as team members feel valued and connected to their work and colleagues, leading to long-term commitment and loyalty.

In Big Tech, the emphasis often lies on outcomes, business impact, and results, sometimes at the expense of the individual. Company culture can disregard the person behind the work, pulling us into a reality where we forget to be human and lose our integrity. But these are the very foundations that underpin success for any team, group, or organization.

The Reality of Big Tech vs. True Team Success

In Big Tech, the emphasis is often on outcomes, business impact, and results. However, company culture can sometimes disregard the person and the individual. Being pulled into that reality, we sometimes forget about being human and lose our integrity. However, these are precisely the underpinnings of success for any group, team, or organization.

Our experience at DueDil shows remarkable things can happen when you prioritize trust, integrity, and trust. A small team of four can achieve what larger teams might struggle with, creating significant business impact and forming bonds beyond the workplace.

Conclusion

In conclusion, building high-performing teams isn’t about complex frameworks or pushing people to their limits. It’s about creating an environment where people trust each other implicitly, integrity is non-negotiable, and achievements are celebrated. The goals, strategies, and performance naturally follow when these elements are in place. When people feel truly seen, trusted, and connected, there’s no limit to what they can achieve together.

So, if you want to build a high-performing team, start by fostering integrity and trust. The rest will follow, and you might find yourself with a dream team that delivers results, creates lasting memories, and impacts far beyond the bottom line.

Master The Behavioral Interview: 5 Effective Storytelling Frameworks

Alex (The Engineering Bolt) ⚡ — Mon, 17 Jun 2024 16:56:40 +0000

The highre up you go in terms of seniority, the more important are behavioral interviews for geting the right approved for the respective role.

To master the behavioral interview in Big Tech companies (Meta, Google, Amazon, Apple, etc) and ensure your storytelling is both impactful and memorable, you can use the following effective storytelling frameworks. These frameworks help structure your responses in a clear, concise, and compelling way.

Join Me

Read more about Engineering Culture in Big Tech, ⚡Newsletter, Twitter and LinkedIn for more Career, Leadership and Growth advice.

1. STAR Method

The STAR method is a widely recognized framework that helps structure your answers to behavioral interview questions.

Situation: Describe the context within which you performed a task or faced a challenge at work. Be specific and provide enough detail to give the interviewer a good understanding of the situation.
Task: Explain the actual task or challenge that was involved. What needed to be done?
Action: Detail the specific actions you took to address the task or challenge. Focus on what you did, rather than what your team or coworkers did.
Result: Share the outcomes or results of your actions. Quantify your success with numbers or percentages if possible, and explain what you learned from the experience.

The Downside of the STAR Method

The STAR (Situation, Task, Action, Result) method is widely used for structuring responses in behavioral interviews. While it is effective in helping individuals organize their thoughts and provide comprehensive answers, there are some drawbacks to this approach. One significant issue is the potential for redundancy between the "Situation" and "Task" steps.

Key Issues with the STAR Method

Redundancy between Situation and Task:
- Repetition: The "Situation" step asks for context, which often naturally includes the "Task". For instance, when describing a project, the speaker will inherently mention their role and responsibilities, which overlaps with the "Task" step.
- Confusion: Candidates may become confused, leading to repetitive information that can detract from the clarity and conciseness of their response.
Over-structuring Responses:
- Rigidity: The strict adherence to the STAR format can sometimes make responses feel mechanical or overly rehearsed. This rigidity can prevent candidates from expressing their experiences in a natural and engaging manner.
- Missed Nuances: Important details and nuances might be overlooked if the candidate focuses too heavily on sticking to the STAR structure rather than telling a compelling story.
Focus on Process Over Outcome:
- Lack of Emphasis on Results: Sometimes, the emphasis on Situation and Task can overshadow the more critical aspects of Action and Result. The outcome and the impact of the actions taken are often more important to interviewers than the initial setup.
- Imbalance: There can be an imbalance in the response, where too much time is spent on setting up the context and not enough on the actions taken and results achieved.

2. PAR Method

The PAR method is similar to the STAR method and stands for Problem, Action, Result. During a behavioral interview the interviewer would be able to follow the story more easily and this makes the framework clearer for the interviewee.

Problem: Outline the problem or challenge you encountered. Set the scene by describing the context.
Action: Describe the specific actions you took to resolve the problem or address the challenge.
Result: Share the results of your actions, focusing on the positive outcomes and any lessons learned.

3. CAR Method

The CAR method stands for Challenge, Action, Result, and is another framework similar to STAR and PAR.

Challenge: Describe the challenge or situation you faced. What made it difficult or significant?
Action: Explain the actions you took to address the challenge. Be specific about your contributions.
Result: Detail the outcomes of your actions, emphasizing the impact and what you achieved.

4. SOAR Method

The SOAR method stands for Situation, Obstacle, Action, Result. This method is useful when you want to highlight how you overcame a particular obstacle.

Situation: Set the context by describing the situation.
Obstacle: Identify the obstacle or challenge you encountered.
Action: Explain the actions you took to overcome the obstacle.
Result: Share the results of your actions, focusing on the positive outcomes.

5. SAR Method

The SAR method stands for Situation, Action, Result, and is a simplified version of the STAR method.

Situation: Describe the situation or context.
Action: Detail the actions you took.
Result: Highlight the results of your actions.

Tips for Effective Storytelling in Behavioral Interviews

Be Concise: Keep your stories focused and to the point. Avoid unnecessary details.
Be Specific: Provide concrete examples and quantify your results when possible.
Be Honest: Authenticity is crucial. Don't exaggerate or fabricate your experiences.
Practice: Rehearse your stories so you can deliver them smoothly and confidently.
Tailor Your Stories: Choose stories that are relevant to the job you're applying for and that highlight the skills and qualities the interviewer is looking for based on the question.

Furthermore, it wouldn't be inaccurate to claim that many prospective programmers envision a six-figure salary when considering a job at Google. Many engineers are still unsure about Google's compensation scale for various levels, from Google entry-level software engineers to more advanced-level engineers' salaries in software engineering. Read below to learn more about a Google-level software engineer's role and salary.

What are Software Engineer Levels?

Software engineering jobs are usually classified into entry-level, mid-level, and senior-level. Furthermore, job levels or grades exhibit your experience, seniority, or extent of accountabilities, along with the appropriate salary band. Therefore, we can say that the higher the software engineer's job level, the more responsibilities.

In addition, leading companies are better placed to decide salary ranges, assign duties, and evaluate impact. They describe a company's authority levels and assist in building a fair wage system with constant possibilities for advancement. Moreover, software engineering job levels help businesses simplify their recruitment procedures and promote strategic decision-making regarding retention, promotions, or even termination of employees.

What are Google Software Engineer Levels?

Google software engineer levels are usually based on a tier-based remuneration system. Multinational corporations like Google use this method because their hierarchy is more extensive. Besides, a scale system also guarantees that every employee within the business earns a similar average salary at equivalent levels.

Likewise, to comprehend how much you can hope to earn, it is vital to understand the software engineer levels at Google. Generally, there are nine Google software engineering levels, which are as follows:

Software Engineer II (Level 3 | 0–1 year of experience)
Software Engineer III (Level 4 | 2+ years of experience)
Senior Software Engineer (Level 5 | Manager I equivalent)
Staff Software Engineer (Level 6 | Manager II equivalent)
Senior Staff Software Engineer (Level 7 | Senior Manager)
Principal Engineer (Level 8 | Director)
Distinguished Engineer (Level 9 | Senior Director)
Google Fellow (Level 10 | Vice President)
Google Senior Fellow (Level 11 | Senior Vice President)

In addition, most software engineers at Google operate at a lower level in the hierarchy. And many challenges are getting promoted above the level of Staff Software Engineer at Google. One of the prominent reasons for this could be a shortage of employment opportunities, so only the best get a raise to senior engineers or higher.

What is Google's Process for Determining Software Engineer Levels?

Speaking of Google, the most significant tech business in the world, its organizational structure was created to encourage efficiency and innovation. As a result, Google divides its software developers into groups according to the tasks they complete. Much transparency is also present, and Google's business structure encourages a continuous exchange of ideas and knowledge among all management levels. Additionally, Google's software engineering levels are often determined by two key variables, ladder and level, after evaluating the person's work position and skill level.

Google Level Grading Factors

Here are some factors Google considers when determining the software engineering levels in the company.

1. Interview Performance

When hiring for different software engineering levels, the recruitment team at Google evaluates your performance based on features like general intellectual ability, role-related understanding, leadership attributes, and cultural fit. Based on this feedback and the conclusive suggestions from the recruiters, Google's hiring panel allocates you a Google software engineer level that defines your duties and the salary band.

2. Past Project Experience

Graduates with Ph.D. or MS/BA degrees without industry expertise usually get hired for entry-level software engineer Google jobs. However, note that higher years of expertise are not linked with higher job levels at Google. For example, if you hold years of knowledge but your interview performance is poor, there are higher odds of rejection than getting employed at a lower level.

3. The skill set of the employee

Google seeks out creative and intelligent applicants with an increased concentration on excellence. In addition, their levelling approach estimates the impact of an applicant with better aptitudes during technical contributions to the company.

Besides, the recruitment team at Google usually hires talented candidates who are willing to upskill themselves and proactively react to the global industry. Thus, whether you get a senior software engineer post at Google or an entry-level position, your interview performance and the ability to handle projects can help you scale up to the job level you want.

Task: My job was to help out with the coding and participate in meetings where we discussed various features we thought would be cool to include in the app.

Action:

General Participation: I did some of the coding, wrote a few tests, and reviewed code from other team members now and then. I also sat in on the planning meetings.
Collaboration: Worked alongside the rest of the team in a supportive capacity, helping where I could with the app's development, but I didn't lead any part of the project myself.

Result:

The app was eventually launched and was pretty well-received from what I remember. I think it got a decent number of downloads and people in the company seemed happy with our work.

This response is considered "Bad" because it fails to convey meaningful specifics about what the app was, the candidate's actual contributions, or the skills they applied. It lacks details on the technical challenges faced, how they were addressed, and the success metrics of the product launch. The actions described are passive and do not highlight the candidate's initiative or impact. Overall, this answer does not demonstrate the candidate's capabilities or provide convincing reasons why they would be a valuable addition to the team. The answer is too generic, suggesting a lack of preparation or inability to articulate one's experiences effectively, which are critical red flags in an interview setting.

STAR Answer: Good Level

Situation: Last year, my previous company, a mid-sized tech startup, decided to tap into the project management market by developing a new task management app. The goal was to create an app that not only addressed the basic needs of task management but also incorporated AI to predict task durations and recommend resource allocations.

Task: As a software engineer, I was tasked with leading the backend development team. My responsibilities included designing the database schema, implementing the server logic, and integrating AI features that our data science team developed.

Action:

Technical Implementation: I started by designing a robust database schema that could handle large volumes of data efficiently. For the server logic, I implemented RESTful APIs using Python and Flask, which I chose for their simplicity and scalability.
Team Coordination: I held bi-weekly meetings with the front-end team to ensure our work was closely aligned. This helped in smoothing out any potential integration issues early in the development process.
AI Integration: The integration of AI features was challenging. The models our data scientists created were sophisticated, but deploying them into a production environment required significant adjustment. I collaborated closely with the data science team, setting up a middleware layer that could preprocess data to be fed into the AI models and handle the output predictions.

Result:

Our app was launched on schedule and within the initial budget. It featured high performance and reliability, handling up to 10,000 users simultaneously at launch.
Post-launch, we received positive feedback from users about the AI features, noting that the predictions were helpful and reasonably accurate.
The app has maintained a 4-star rating on various software review platforms and has onboarded 3,000+ companies to date.
