So you’ve decided it’s finally time to get serious about interview prep. No more winging it, no more hoping the recruiter skips system design questions, no more “I’ll just figure it out during the interview” (spoiler: you won’t).
You start Googling resources and bam, you stumble on Hello Interview, a relatively new platform promising to help you crush technical interviews with curated guides, mock interviews, and system design practice.
But here’s the real question: Is Hello Interview worth it? Or is it just another subscription you’ll add to the pile, right next to your half-finished Udemy courses and that Pluralsight trial you forgot to cancel?
I’ve been around the block, coding interviews, design interviews, and the endless grind of trying to find resources that actually stick. So let’s break this down, dev-to-dev.
What Hello Interview Offers
Hello Interview is laser-focused on one thing: interview preparation for software engineers.
At its core, Hello Interview concentrates on system design walkthroughs, mock interviews, and structured frameworks for behavioral and technical rounds.
Instead of drowning you in thousands of random problems, it curates common interview-style scenarios. Think designing Twitter, Uber, chat systems, rate limiters, or scalable APIs. The emphasis is on how to communicate trade-offs clearly and structure your thinking in a 45-minute conversation.
Here’s a clearer breakdown:
| Feature | What It Actually Means in Practice |
|---|---|
| System Design Guides | Structured walkthroughs of popular high-level design problems |
| Mock Interviews | Real-time practice sessions that simulate interview pressure |
| Behavioral Frameworks | STAR-style and leadership-based preparation |
| Curated Roadmaps | A suggested path to avoid random resource hopping |
The value proposition is clarity and focus. It tries to eliminate noise.
Is Hello Interview Worth It for System Design?
If your main concern is system design interviews, Hello Interview does provide structured guidance. It walks through common architectures and shows how to break problems into components, discuss scaling, and explain trade-offs.
However, most of the learning is text- and video-based.
That means the platform helps you understand patterns conceptually. But whether you retain and internalize them depends heavily on how actively you engage.
Reading about designing YouTube is different from designing it yourself under time pressure.
That’s the gap most developers discover too late.
Pricing: Is Hello Interview Expensive?
Pricing changes over time, but Hello Interview typically runs on a subscription model, with mock interviews sometimes priced separately.
Compared to other platforms:
| Platform | Pricing Model | Primary Strength |
|---|---|---|
| Hello Interview | Subscription + paid mocks | Interview structure & simulation |
| LeetCode Premium | Monthly subscription | Algorithm repetition |
| Educative.io | Subscription | Interactive, hands-on learning |
| Coursera | Course-based pricing | Academic-style content |
If you’re stacking subscriptions, costs add up quickly. If you have interviews in the next 1–2 months, the focused structure may justify the cost. If you’re casually preparing without a clear timeline, it becomes harder to justify.
In short, Hello Interview is a targeted investment, not a general learning subscription.
The Pros of Hello Interview
Alright, let’s give credit where it’s due.
1. Interview-Focused Content
Unlike generic learning platforms, Hello Interview is built specifically for interviews. That means everything is geared toward your end goal: not just “understanding system design,” but “being able to talk about system design in a 45-minute interview.”
2. Mock Interviews
This is one of its best features. You can practice with peers or mentors in real interview-style sessions. And trust me, nothing exposes your blind spots faster than stumbling through a mock when the clock is ticking.
3. Curated Guides
If you’re overwhelmed by the thousands of blogs, YouTube videos, and random GitHub repos out there, Hello Interview gives you a more structured way to prepare.
The Cons of Hello Interview
But is Hello Interview perfect? Nope. Let’s be honest.
1. Price Tag
The subscription isn’t cheap. If you’re already juggling LeetCode Premium, maybe a Coursera subscription, and that unused Gym membership, the cost adds up.
2. Passive Learning Trap
Much of the content is still video or text-heavy. You’re reading explanations and watching walkthroughs more than you’re actually coding. And as every developer knows, watching ≠ learning.
3. Narrow Scope
It’s excellent for interview prep, but if you want to actually grow as a developer beyond interviews, like building projects, mastering frameworks, or leveling up in your day job, it’s not really designed for that.
My Honest Answer: Is Hello Interview Worth It?
If your primary goal is to pass technical interviews, especially system design and FAANG-style interviews, then yes, Hello Interview can be worth it.
It gives you structure, curated guides, and the chance to practice realistically. If you’ve got interviews coming up soon, it’s a focused way to prep without drowning in random resources.
But here’s the catch: if you want to actually build long-term coding skills and not just rehearse interview answers, Hello Interview isn’t enough on its own. It’s a good supplement, but not the whole meal.
The Bigger Problem: Passive vs Active Learning
Most developers don’t realize this until it’s too late: technical interviews test application as well as knowledge.
You can read a hundred guides about designing YouTube, but when you’re in the hot seat, you need to actually apply the principles. You need to think aloud, structure tradeoffs, and sometimes even sketch pseudocode.
That’s the problem with purely passive platforms like Hello Interview (and honestly, most video-based learning tools). They prepare you to know, but not always to do.
Enter Educative.io: The Hands-On Alternative
That’s why I always recommend pairing interview-focused platforms with something that forces you to actually practice, like Educative.io.
Here’s why Educative stands out compared to Hello Interview (and even compared to classics like Coursera or Udemy):
- Interactive Coding: Lessons come with in-browser coding environments. You’re not just reading about algorithms, but implementing them right there.
- System Design Coverage: Their Grokking the System Design Interview course is famous for a reason. It covers the same patterns recruiters expect you to know, but in a structured, interactive way.
- Beyond Interviews: Unlike Hello Interview, Educative has paths for web development, machine learning, cloud, and more. You’re building career skills.
- No Setup Hassles: No wasted hours setting up your environment. You just open the course and code.
It’s basically the difference between watching a YouTube video about push-ups vs actually doing push-ups. Only one of those builds muscle.
Hello Interview vs Educative.io
Many developers compare Hello Interview with Educative.io, especially when preparing for system design interviews.
The difference lies in learning style.
| Category | Hello Interview | Educative.io |
|---|---|---|
| Interview Simulation | Strong | Limited |
| Interactive Coding | Minimal | Strong |
| System Design Depth | Interview-focused | Pattern-focused and structured |
| Long-Term Skill Growth | Narrow | Broader |
| In-Browser Coding | No | Yes |
Educative emphasizes interactive learning. Instead of just reading about distributed systems, you engage with structured exercises and guided reasoning. Courses like Grokking the System Design Interview break problems into repeatable design patterns, which improves retention.
If Hello Interview trains communication, Educative trains implementation and structured reasoning.
Ideally, they serve different purposes.
Is Hello Interview Worth It for FAANG?
For FAANG-style interviews specifically, the answer is nuanced.
Yes, it can be worth it, but not as a standalone solution.
FAANG interviews test structured reasoning, system trade-offs, and clarity of communication. Hello Interview helps you practice that format.
But FAANG also tests depth. You need to understand caching strategies, consistency models, partitioning, scaling bottlenecks, and real-world trade-offs beyond surface-level diagrams.
For that, you need deeper hands-on exposure and active problem-solving.
The strongest candidates combine structured interview rehearsal with active coding and architecture practice.
The Bigger Problem Most Engineers Ignore
The real issue isn’t Hello Interview itself. It’s the learning style many engineers default to.
Watching videos feels productive. Reading detailed guides feels productive. But when the interviewer interrupts and asks, “What if traffic spikes 10x?” or “How would you handle data consistency across regions?” — you can’t pause and rewind.
That moment exposes whether you practiced actively or consumed passively.
Hello Interview helps with structure. But structure alone does not replace repeated application.
TL;DR: Is Hello Interview Worth It?
- Hello Interview → Great for interview-focused guides and mock interviews. Best if you have FAANG-style interviews coming up. Weakness: passive learning, narrow scope.
- Educative.io → Great for interactive, hands-on coding and structured interview prep. Stronger for long-term skill-building and real coding practice.
Final Thoughts
So, is Hello Interview worth it? If you’re staring down the barrel of upcoming interviews, absolutely. It’s structured, practical, and helps cut through the noise. But if you want to actually grow as a developer, not just pass the next round, it’s not enough.
That’s where Educative.io shines. It’s hands-on, it’s interactive, and it forces you to code, debug, and learn by doing. Pairing the two can give you the best of both worlds: the pattern recognition from Hello Interview and the actual coding practice from Educative.
At the end of the day, you’ll land jobs not because you memorized patterns, but because you practiced enough to explain, adapt, and implement them under pressure.
Now, if you’ll excuse me, I’ve got another mock interview scheduled, and about five half-finished prep courses side-eyeing me from my dashboard.
