Short and sweet: Best mock interview I’ve ever done. Period.Quote

Lead Architect
DesignGurus matched me with an ex-Amazon engineer who grilled me on CAP theorem and load balancing. We spent half the time debating NoSQL vs. SQL for a social media feed, and the other half optimizing latency. Massive confidence boost. Got an offer from CloudNest three weeks later!Quote
Elena K.
Solutions Architect
I booked a quick coding mock session and the interviewer threw actual FAANG questions at me. It was intense, but afterwards I had a clear list of topics to drill. Wouldn’t have gotten past my coding screen without it!Quote
Priya M.

Solid 10-minute feedback summary after my 45-minute mock. The comments were blunt but useful—stuff like ‘stop using vague terms’ and ‘consider edge cases faster.’ Super concise, exactly what I needed.Quote
David R.
Software Engineer
Short but honest: If you’re serious about cracking FAANG, do these mocks.Quote
Leo Z.
QA Engineer
Did a system design mock for a ride-sharing app. My mentor talked me through API gateways, rate limiting, and said things like ‘don’t forget map services or you’ll tank HFT.’ Totally nitpicked my thought process, but in a good way. I walked into my real interview feeling battle-ready.Quote
Arjun P.
Backend Engineer
Booked a behavioral mock and honestly, it was life-changing. We worked on my STAR answers for leadership questions, and my coach even helped me avoid repeating ‘basically’ every other sentence. Got my first onsite at TechWave, thanks!Quote

Data Engineer
Two sentences: The mock session was exactly like the real thing, and the feedback notes saved my ass.Quote
Carlos V.
Software Developer
I’m a frontend guy, so algorithms are my weak spot. DesignGurus sent me a mock that focused on basic DS&A pitfalls without drowning me in advanced graph theory. Just enough challenge to stretch me, not break me. Passed my ByteCraft screen on the first try.Quote
Aisha N.
Frontend Engineer
Longer review alert: I scheduled three different mocks—coding, system design, and behavioral—over two weeks. First, my coding mock highlighted that I wasn’t thinking about time complexity upfront. Next, the system design session drilled me on data redundancy and consistency models. Finally, the behavioral mock made me reframe my ‘tell me about a time’ stories to be much more concise and impactful. The combined feedback was ridiculously thorough. I ended up getting offers from two companies; couldn’t have done it without these sessions.Quote
Michael T.
Lead Architect
My interviewer was super chill and gave real-world anecdotes when explaining load balancer sharding. Made the whole process less nerve-wracking. Afterwards, I fixed my diagram notation and nailed the actual design interview.Quote
Jenna Y.
Principal Engineer
Booked a late-night slot because I’m on UK time. Support rescheduled within minutes when I realized I had a work conflict. Great customer service, great feedback, great results.Quote
Niam H.
Software Engineer
I did a targeted Google mock that literally asked me the same style of questions I got on my actual phone screen. I kid you not. The prep guide they sent afterward covered points like how Google evaluates code readability and edge cases specifically. Landed my offer two weeks later!Quote
Rahul K.
Software Engineer
My career break left me a little rusty. The DesignGurus mock pointed out that I was using outdated Java 7 syntax instead of streaming APIs, and they helped me modernize my approach. Landed a role at FinVital after just one session!Quote
Emily F.
Software Engineer
Went for a Meta mock because I was targeting their infrastructure teams. They asked about scaling Newsfeed and caused me to rethink how I handle eventual consistency. I passed the Meta screen; owe it to the detailed mock!Quote

Quick version: Awesome mock, flexible scheduling, honest feedback. Helped me jump from mid-tier offers to FAANG-level interviews.Quote

Frequently Asked Questions - Tech Mock Interviews

A Tech Mock Interview is a simulated environment designed to prepare you for any technical interview format—coding, system design, or behavioral. In a System Design Mock Interview, you focus on large-scale architecture, trade-offs, and distributed systems concepts. A Coding Mock Interview hones your data structures and algorithm skills under FAANG-level problem-solving constraints. All our Tech Mock Interviews are led by FAANG engineers, so you’ll experience the exact rigor of an on-site FAANG Mock Interview.

Our FAANG Mock Interviews are run by experienced engineers from top tech companies like Google, Amazon, Meta, Microsoft, and Apple. They have personally interviewed candidates at these companies and know exactly what hiring panels look for. You’ll get insider tips on tackling “FAANG-style” questions, avoid common pitfalls, and learn how to structure high-level system design diagrams.

Before your session, review fundamental system design concepts—scalability, load balancing, caching, and database sharding—for a System Design Mock Interview. For a Coding Mock Interview, practice core algorithm patterns like two-pointers, sliding window, and binary search. In both cases, go through our curated “Mock Interview Prep Checklist,” available in the resources section, to ensure you’re ready to simulate a real FAANG Mock Interview.

In our Coding Mock Interview, you can choose from Python, Java, C++, JavaScript, Go, and more. Our FAANG Mock Interviewers will replicate either a whiteboard format (for on-site interviews) or an online coding platform (for remote interviews), depending on the target company’s standard. Additionally, you’ll receive feedback on your coding style, complexity analysis, and communication clarity at the end of the session.

Yes—you can book stand-alone Coding Mock Interviews and System Design Mock Interviews, or opt for our combined “Complete Tech Mock Interview Package” at a discounted rate. This way, you’ll practice both critical skills—problem-solving algorithms and high-level architecture—in separate 60-minute sessions with dedicated FAANG interviewers.

All mock interviews are conducted online via secure video conferencing. When you book, you can filter interviewers by their company background (e.g., Google, Amazon) to align with your target FAANG Mock Interview. We also match you by role level (Entry, Mid, Senior) to tailor the difficulty and focus of your tech mock interview.

Absolutely. Post-interview, you'll receive comprehensive feedback highlighting your strengths, areas for improvement, and strategies to enhance your performance in real interviews.

Not at all. Whether you're just starting out or already have experience, our mock interviews are designed to meet you where you are. They're a great way to build confidence, get structured feedback, and accelerate your learning - no matter your starting point.

Yes, you can reschedule or cancel your mock interview with at least 24 hours' notice. For urgent last-minute changes, please reach out to our team directly.

You'll get the most out of your mock interview if you've done some basic preparation, like reviewing key concepts or practicing a few problems. If you're just getting started and feel completely unprepared, consider taking a coaching session first. Mock interviews are most effective when you're close to being interview-ready and want to test yourself, get feedback, and fine-tune your performance.

Mock interviews provide a realistic practice environment, helping you build confidence, improve problem-solving skills, and refine your communication. This preparation significantly enhances your performance in actual job interviews.
