How the AI mock interview works

Rehearse the round you're actually about to have.

Build the interview first — role, round, depth, stack, focus — save it, and run timed sessions against it. It's the difference between practising interviews and practising this one.

What is a CodeKairo mock interview?

A mock interview is a timed, AI-led interview built from your setup: one of 39 roles and 16 rounds (coding, system design, behavioural, HR, resume deep-dive and more) or your own, a depth from Beginner to Advanced, your seniority, stack and focus areas. It runs as a written round of seven questions or a voice round of 10, 20 or 30 minutes, and ends in a report scoring each answer out of 10 and naming what you were shaky on. Setups are saved as templates to rerun before the real thing. From 1 January 2027 the Free plan includes two rounds a week and paid plans more; until then every limit is lifted.

01How it works

Describe the interview. We'll hold you to it.

The builder asks the questions a good coach would: what role, which round, how senior, which stack, where do you want pressure. It takes about a minute, and the result is a template you can run as many times as you need.

  • 01

    Pick the role and round

    39 roles and 16 rounds, one of six one-click presets, or your own words for either. A backend system-design round and a product manager's behavioural round are not the same interview, so they are not built as one.

  • 02

    Set the depth and focus

    Beginner, Intermediate or Advanced — about 25, 40 or 55 minutes written — and your seniority from intern to lead; then, if you want them, up to eight focus areas, a style (Mixed, Technical-heavy, Debugging-heavy, Behavioural + Technical or Rapid screening) and a stack.

  • 03

    Sit the round

    Written: seven questions one at a time, code in the editor or prose in the answer box. Voice: a 10-, 20- or 30-minute conversation over your microphone, with follow-ups, in English, Hindi or Hinglish.

  • 04

    Read the report, then rerun

    Every answer scored out of 10, with a readiness band, strengths, weaknesses and next steps. Starting a round saved its setup — up to thirty per account — so the night before, the same interview is one click away.

Who it is for

Anyone who knows which interview is next and wants to rehearse that one rather than interviews in general: a fresher before a campus drive, an SDE facing a system-design loop, or a data analyst, QA engineer or product manager whose rounds are not coding rounds.

02Why setup matters

Specific beats general

A system-design round for a backend role at four years' experience asks different things than 'a technical interview'. The setup is how we know.

Length you can see

The builder says how long a round runs before you start — seven questions and about 25, 40 or 55 minutes written, or the 10, 20 or 30 minutes you pick for voice.

Templates, not one-offs

Save the setup. Rerun it the night before. Edit it when the job description changes.

03Questions

Can I keep more than one setup?

Do interviews affect rating?

Is it only for engineers?

How the AI mock interview works

Build the interview you are about to have — 39 roles, 16 rounds, 3 depths, your stack — and run timed, AI-led rounds that end in a scored report.

What is a CodeKairo mock interview?

A mock interview is a timed, AI-led interview built from your setup: one of 39 roles and 16 rounds (coding, system design, behavioural, HR, resume deep-dive and more) or your own, a depth from Beginner to Advanced, your seniority, stack and focus areas. It runs as a written round of seven questions or a voice round of 10, 20 or 30 minutes, and ends in a report scoring each answer out of 10 and naming what you were shaky on. Setups are saved as templates to rerun before the real thing. From 1 January 2027 the Free plan includes two rounds a week and paid plans more; until then every limit is lifted.

How it works

  1. Pick the role and round. 39 roles and 16 rounds, one of six one-click presets, or your own words for either. A backend system-design round and a product manager's behavioural round are not the same interview, so they are not built as one.
  2. Set the depth and focus. Beginner, Intermediate or Advanced — about 25, 40 or 55 minutes written — and your seniority from intern to lead; then, if you want them, up to eight focus areas, a style (Mixed, Technical-heavy, Debugging-heavy, Behavioural + Technical or Rapid screening) and a stack.
  3. Sit the round. Written: seven questions one at a time, code in the editor or prose in the answer box. Voice: a 10-, 20- or 30-minute conversation over your microphone, with follow-ups, in English, Hindi or Hinglish.
  4. Read the report, then rerun. Every answer scored out of 10, with a readiness band, strengths, weaknesses and next steps. Starting a round saved its setup — up to thirty per account — so the night before, the same interview is one click away.

Frequently asked questions

What does a session actually look like?
A timed interview built from your setup. The role, round and depth decide the shape; the stack and focus areas decide what it drills into. Save the setup first and you can rerun it before the real thing.
Can I keep more than one setup?
Yes. Templates are saved to your account — one for the front-end role, another for the system-design loop — and any of them can be edited or reused in one click.
Do interviews affect rating?
No. Rating is driven by challenge submissions. Interview practice is its own track, tied to templates and sessions.
Is it only for engineers?
Mostly, but not only: Data Analyst, QA Automation and Product Manager are first-class roles with rounds that fit them.
