Why peer interviews work

Most interview practice is solo: you solve problems alone, in silence, with a Run button. A peer brings back what makes interviews hard: someone watching you think, asking why you chose a heap, and noticing when you go quiet for five minutes.

Sitting on the other side helps just as much. Running a round with a rubric in front of you shows you exactly what interviewers listen for, and you stop making the same mistakes yourself.

What usually goes wrong with peer mocks, and how Practick handles it

• Unprepared interviewers: every question comes with an interviewer guide, with the answers to clarifying questions, follow-ups with expected answers and a scoring rubric
• No-shows: three strikes and an account is suspended, and the person left waiting gets their credit back
• One-sided effort: credits are conserved one for one, so everyone who gets interviewed has given an interview too
• Vague feedback: feedback is scored on technical ability, communication and problem solving, and you cannot book again while you owe feedback on an interview you ran

Peer mocks compared with the other options

Friends are easy to ask but rarely push back. AI interviewers are always available but cannot judge how you communicate. Paid sessions with senior engineers give the most experienced feedback, at a price per session. Peer mocks are the free way to practise with a real person, as often as you are willing to give the same time back.

Getting the most from a peer round

• As the candidate, think out loud from the first minute
• As the interviewer, follow the guide on when to give a hint, and write the feedback down
• Ask for one specific thing to fix, not a general impression
• Swap seats often: the interviewer seat teaches as much as the candidate one

Frequently asked questions

Is a peer as good as a professional interviewer?

Not always as experienced. But with a guide and rubric for every question, a peer can run a realistic round, ask the right follow-ups and score you against the same criteria. For regular practice, getting many realistic rounds in usually matters more than who runs each one.

What can I practise with a peer?

Data structures and algorithms, system design (HLD), low-level design and frontend engineering. The bank has 600+ DSA and system design questions, plus low-level design and frontend rounds.

When are peer interviews scheduled?

Interviews run on Tuesday and Sunday evenings, with slots at 9 PM and 10 PM IST. You both join a video call in the browser.

Is it free?

Yes. You give an hour to get an hour, and new accounts start with one free credit so the first interview can be yours.
