In a previous article I wrote about the 2 types of software engineering interviews. My point there was to distinguish between the two primary types of interviews you can expect from software engineer hiring managers. There’s the data structures and algorithms approach and there’s the build something or talk about what you’ve built approach. It’s not completely binary and in some interviews you may be asked to do both. There are also system design and behavioral questions to account for.
Technical interviews are hard. Investing in software engineers can be trying. Hiring, employee retention and business costs all factor in to who gets picked. As software engineers we need to know what to expect. Each person is taking their own path to career growth. My intention with listing out these resources is to provide for those navigating the job market terrain and to hold these resources up as a reflection for the industry. These are some study resources that you many find helpful in your journey.

Side projects are a great way to test out your skills and try new things in a low to no pressure environment. Sometimes interviewers will be even more interested in your side projects than the work you did at your 9-5 job! If you don’t have any traditional work experience in the tech industry making a web project from scratch is a great way to demonstrate what you’re capable of. Below are a few sites and articles to reference when building a side project:
- Indie Hackers: is a community for people looking to build online projects that generate revenue. It’s a vibrant, supportive community where you can share your projects and progress.
In the article How to build a startup — without quitting your day job Aytekin Tank, founder of JotForm outlines a few tenants to live by with side projects:
- Side projects increase creativity
- Find the time
- Finding the need: deliver extreme value
- Make it fun
- Relax with imperfection
In this post Tanner Christensen outlines How to Talk About Your Side Projects. Snippet from the article: “Talk about your side projects whenever you get a chance”.
- Start with the problem
- Define your approach
- Share the challenges you faced
- End with the results
- Follow-up with what you would do differently
If you’d like to dive more into storytelling and strategic narrative I highly recommend following Andy Raskin for tips :)
There doesn’t seem to be any shortcut for learning data structures and algorithms besides grinding it out. The problems are not always easy but the solutions generally do follow defined patterns. Learning the patterns takes a lot of work and practice. My favorite blog posts about the tech interview prep process come from Ali Mir, Software Engineer at Facebook. They’re not long articles; they’re straight to the point without a lot of fluff.
These are some commonly agreed data structures it’s helpful to know going into technical interviews:
- Dynamic Array
- Linked List
- Stack & Queue
- Hash Tables
- Binary Search Tree
- Binary Heaps & Priority Queue
These are searching and sorting processes to be aware of in technical software engineering interviews..
Breadth First Search (BFS)
Depth First Search (DFS)

We've shared some notes about how to land a technical internship in the Bay Area. Tbh though I've never done an internship and the competition seems fierce. I think a lot of the same rules apply to finding internships as finding jobs, though more focus on deadlines and internship-focused positions. Looking forward to learning and sharing more about the tech internship process in the Bay Area. 📈
