What you get

Everything for the prep loop — question, answer, grade, improve.

Rubric grading, not a vibe check

Every open-ended and behavioural answer is scored against weighted concepts — with a verdict and evidence per concept, honest feedback, and a sample strong answer to learn from.

Every question type

Technical and behavioural (STAR) questions, plus recruiter-style aptitude — numerical, logical, verbal, and abstract, including complete-the-pattern and diagram questions.

🎙

Voice interviews

Practise like the real thing: the question is read aloud, you answer out loud, and your spoken answer is transcribed and graded on the exact same rubric — a full spoken mock, not just dictation.

See yourself improve

A progress dashboard, per-field readiness scores, day streaks and XP, and spaced repetition that resurfaces the topics you struggle with.

Prep for a specific job

Paste a job description — get the matched skills, a gap analysis against your history, and a targeted question set for that exact role.

Full interviews, end to end

Run a timed mock, or paste the focus areas from an interview invite for a tailored role interview — each ends in a coaching report and saves to your revision.

Defend your CV

Upload your CV and answer the questions a sharp interviewer would actually ask — probing your metrics, your standout projects, and your gaps — with graded coaching on each.

Coaching from feedback

Paste the feedback a recruiter gave you — or just flag the areas you struggled with — and get a targeted, self-tracking study plan that maps your weak spots to exactly what to practise next.

Build & share your own tests

Write your own questions — multiple-choice, aptitude, open-ended, even diagrams — and assemble them into timed tests. Take them, retake to track your progress, and share a whole test with a friend.

A bank that keeps growing

Questions are AI-generated and human-reviewed, added by hand, or bulk-imported — across DevOps, Kubernetes, Docker, Linux, networking, databases, and more.

Pricing

Start free. Upgrade when it counts.

Free covers the core prep loop — practice, aptitude, classes, review, JD-aware prep and skill badges. Pro takes the grading cap off and adds mock interviews, progress & readiness analytics, and authoring your own multiple-choice questions. Ultimate adds the AI that builds your prep — fresh questions per job description, voice interviews, CV Defense, coaching plans from interview feedback, and AI that writes the answer key for questions you author — plus the tools for assessing other people: employer screening and team cohorts.

Both paid plans bill monthly or yearly — yearly saves you two months.
