Mock interviews for developers

Practise the interview
you're actually
going to sit.

Build a test on the concepts you keep fumbling, take it under proctored conditions, and get a readiness report that names your gaps instead of handing you a number.

How it works

Create, take, get reviewed.

Build the test

Pick a subject, or just the concepts you keep getting wrong. Set difficulty, or let it calibrate from the experience on your profile. Every automatic choice tells you its reasoning in one sentence.

Sit it properly

Fullscreen, on a clock, with tab switches logged and a two-strike warning. Answers autosave as you type, so a refresh drops you back on the same question with the timer where it should be.

Read the report

Objective questions score immediately. Your code and written answers get reviewed for correctness, edge cases and complexity — then it rolls up into a readiness verdict with the concepts to go fix.

Question types

Seven formats, because a real loop is never all multiple choice.

Objective questions are scored directly. Everything you write or code is read and reviewed — that is where the report gets its detail.

01Multiple choiceOne correct option, with distractors built from the mistakes people actually make.scored

02Multiple correctSelect all that apply. Partial credit, with a penalty for wrong selections.scored

03Output predictionRead the snippet, say what it prints. No running it first.scored

04Short answerTwo or three sentences, reviewed for the reasoning rather than the wording.reviewed

05CodeImplement the function in the editor. Reviewed for correctness, edges, and style.reviewed

06Problem solvingA scenario from a real codebase. Show how you would diagnose it, not just the fix.reviewed

07DSAConstraints, examples, and a complexity target — the whiteboard round, in an editor.reviewed

The readiness report

A verdict you can act on.

Not a percentage in isolation. The report ties every point back to a concept, so “ready with gaps” arrives with the list of gaps — and a button that builds your next test out of them.
