DSA Mock Interview with Nitesh Sinha

Frontend roles at top companies still test DSA, and many frontend developers underprepare for it. In this round, I'll evaluate you the way a real interviewer does: your approach, communication and code, not just the final answer.

The problems I give aren't copied from popular lists, so you can't rely on having seen them before. With good problem-solving fundamentals, you'll be able to work through them, and that's what a real interview tests.

What you'll get:

• 1–2 original, interview-level DSA problems
• Feedback on your problem-solving approach and complexity analysis
• Tips on thinking out loud and communicating with the interviewer
• The topics you should focus on for your target companies

Why me:

• Senior Frontend Engineer at Zomato who applies DSA in real product work, not just on LeetCode
• I know how product companies test DSA, including the frontend twist: trees for DOM-like data, caching, debouncing and scheduling
• Optimisation is my core strength: I'll push you from brute force to optimal and make you justify every time and space trade-off
• Original problems pitched at the level of Google, Flipkart, Uber and Zomato rounds
• Honest, specific feedback, not just a pat on the back
