System Design Mock Interview for SDEs 🏗 with Sourav Dey

Most people grind DSA until they are comfortable, then walk into system design having read a few blog posts. It is the round that most often separates a yes from a no at senior level, and the one people practise least.

This is a real 60 minute round. I give you a deliberately ambiguous problem, you drive, and I push where an actual interviewer pushes: scale, failure modes, the trade-off you glossed over, the question behind the question.

Then honest feedback. Where you lost the thread, what you assumed without saying out loud, which trade-offs you never surfaced, and how a strong candidate would have structured the same answer.

Written feedback within 24 hours, including the specific things to practise before the real one.

Want a machine coding round instead? Say so when you book and we will do that.

Best for: Engineers with 1 or more years interviewing at product companies / service companies
