Walk me through how you'd design a URL shortener that scales to 10M req/day.

I'd start by separating the write path from the read path. For writes, a base62 encoder over a sharded counter…
Interviewer
Good. Why a counter and not a hash? Walk me through the trade-offs.
You
Hashes give you idempotency on the same URL but you risk collisions and longer keys…
Interviewer
Nice trade-off framing. Now — how would you handle hot keys in cache?

Features

Everything you need to prep, practice, and pass.

An AI that listens, asks follow-ups, scores against rubrics, and tells you exactly what to fix before your next round.

Real-time voice interviewer

Sub-50ms streaming voice powered by Deepgram + ElevenLabs and Claude Sonnet 4 — feels like a human round.

Rubric-based scoring

Every answer scored against a 6-axis rubric: clarity, depth, structure, correctness, communication, confidence.

Proctoring built-in

Face presence, tab-switch, multi-person and audio anomaly detection — exam-grade integrity, no extra software.

Personalised study plans

After every session you get a weekly plan: skill gaps, recommended topics, and the next interview to book.

Resume & skill graph

Upload your resume, we extract skills, embed them, and match every interview to your strongest and weakest areas.

Mock exam patterns

UPSC Prelims/Mains, GATE, NEET, CAT, CLAT, SSC, banking — full timing, marking, and negative-mark rules.

India-first compliance

DPDP Act 2023 compliant. Data hosted in AWS Mumbai. Encryption at rest + in transit. No data leaves the VPC.

Passwordless sign-in & passkeys

Email one-time codes, optional 2FA via Google Authenticator, and WebAuthn passkeys — Face ID, Touch ID, or a security key. No passwords to leak.

Behavioural rounds

STAR-method coaching, follow-up question generation, tone and filler-word feedback.

Detailed reports

Sectional scores, hiring readiness, integrity flags, transcript with annotations — share with mentors or recruiters.

Real feedback from real candidates.

I used to freeze on system-design questions. Three weeks of PrepGym and I cleared a Razorpay SDE-2 round on the first attempt.

The behavioural rubric is brutal in the best way. Got real, structured feedback I never got from peer mocks.

We rolled it out to 1,200 final-year students. Placement training time dropped by 60% — and our average offers went up.

The proctoring is tighter than what I had in my real GATE mock series. Felt like a real exam hall.

I cleared UPSC Interview after seven personality-test mocks here. The follow-up questions made all the difference.
