Question banks are dead.The interview answers back.

Your first mock is free.
You said you cut API latency by caching. What did you cache, and how did you invalidate it?
We cached user profiles in Redis with a five-minute TTL, and busted the key on every profile write.
Five minutes is long for profiles. What happens if a write and a read race?

Who it's for
Mock loops for every seat at the table.
Students
Campus placement. The real one.
- Pick your branch and stream; see only the drives you're eligible for
- Rounds run in drive order: aptitude, coding, then interviews
- Every round's result in one place, with your trend
- Wifi drops? You resume on the same question
Professionals
Built from the job you're applying for.
- Paste the job description; questions are built from it
- Asked about real systems, trade-offs and failures
- Product, analytics, consulting and core-engineering roles get role-specific questions
Colleges & centers
Your batch says they're ready. Now you'll know.
- Bulk-import students from a sheet and invite the whole batch at once
- Upload your syllabus: ~70% of each interview is on finished modules, ~30% on the student's own projects
- Set interview length (10–60 min) and level per batch
- See readiness by branch, batch and module, and who started, finished and cleared
- Every mark quotes the student's words; a PDF per student, CSV for the batch
Your data
Plain rules. Written down, not buried.
- Kept 90 days, at most
- Interview recordings are never kept longer than 90 days. Close your account from settings, any time.
- Accent is never marked
- Built for Indian English. You're scored on what you know, not how you sound.
- Centers see the report, not your files
- Score, fixes, quotes and the conversation. Never the resume file, a recording or your date of birth.
- Safe by default
- HttpOnly sessions and rate-limited sign-in. Students under 18 need guardian approval before a live interview.
Is this better than practicing with a friend?
A friend can't run a full mock at midnight, pick up after dead wifi, or score every answer against the same written rubric. A friend is still better for moral support.
What if my wifi drops mid-interview?
The interview clock stops, and you resume on the same question with the conversation intact.
Is it useful for non-tech roles?
Yes. The professional interview is built from the job description you paste, so product, analytics, consulting and core-engineering roles get role-specific questions.
Which languages are supported?
Every round, from aptitude to HR, runs in English. Accent and grammar are never scored.
What does a student need?
A laptop or phone with a mic and camera, and Chrome or Edge. Nothing to install.
How long do you keep recordings?
No longer than 90 days, and you can close your account from settings at any time.
Can a college or coaching center use it?
Yes. Centers invite batches from a sheet, see batch readiness, and read the evidence behind every score. Your first batch is a free pilot.
