Talk through real technical questions with an AI interviewer that listens, asks follow-ups and scores your answers, then shows you exactly where to improve.
Practice for these roles
Most candidates walk in under-rehearsed: they know their craft, but they haven't practiced saying it out loud, under pressure, with someone pushing back.
Reading sample answers isn't the same as answering out loud, on the clock.
Friends say "that sounded great." They can't tell you what an interviewer is really scoring.
Real interviewers probe. Scripted practice never teaches you to think on your feet.
Without a baseline, every practice session feels like starting over.
Every answer is scored against a rubric for the role, then translated into specific, usable advice for your next attempt.
Illustrative scores, not a real user
Clear trade-offs when comparing storage options. Next time, say how you would handle cache invalidation under concurrent writes.
No scripts to memorize. You speak (or type), KickOff does the rest.
Pick one of 10 roles, a level (Beginner, Intermediate or Advanced), 3, 5 or 8 questions and how you want to answer. Add a resume if you like.
The interviewer asks each question out loud. Speak your answer, or type it if you prefer; it listens, asks follow-ups and adjusts as you go. Sessions last up to 40 minutes.
As soon as you finish: an overall score, topic scores, strengths and focus areas, and the points a strong answer would cover.
Your history and dashboard show the trend. Complete enough full interviews of a role to earn a Foundation or Professional practice certificate.
10 roles, 30 curated questions each, and a report that tells you what to work on next.
Explore all rolesStatistics, machine learning, model evaluation and experimentation, explained out loud the way you would to a hiring panel.
Everything you need to practice deliberately, and none of the scheduling or awkwardness of a human mock.
Answer out loud, or type if you prefer. The interviewer asks follow-ups based on what you actually said, then moves on when you are done.
Questions get harder when you are doing well and easier when you are struggling, so each session stays useful.
Per-topic scores, a skills radar, strengths and focus areas, so you know what to practice next.

A dashboard with your score trend, practice streak and recent sessions, plus a filterable history.
Practice any time you like, with 3, 5 or 8 questions per interview and up to five interviews in any 24 hours.
Complete enough full interviews of a role with solid scores and earn a Foundation, then a Professional, practice certificate with a public verification code. Certificates show practice readiness, not an employer credential.
Candidates use KickOff to turn "I hope I'm ready" into "I've done this before."
"I'd been rejected after three final rounds. The report showed I was rambling and never quantifying impact. Six sessions later, I had two offers."+22 points in 3 weeks
"The follow-up questions feel uncomfortably real. By the time I sat in the actual loop, nothing surprised me."3 offers in one month
"We run every cohort through KickOff before mock day. The difference in confidence, and in how they structure answers, is night and day."240+ students coached
Short, practical reads you can use before your next practice session.
A simple 60-second structure that keeps the interviewer leaning in instead of checking the time.
Stop jumping straight to boxes and arrows. Use this order to sound senior before you name a single component.
A report is only useful if it changes what you do next. Here is how to turn scores into a weekly routine.
KickOff isn't a question bank or a one-off mock. It's a practice loop you can run until the real thing feels routine.
| What matters | Practice alone | Human mock | KickOff |
|---|---|---|---|
| Real interview pressure | No | Yes | Yes |
| Role-specific questions | Sometimes | Sometimes | Yes |
| Instant, scored feedback | No | Sometimes | Yes |
| Relevant follow-up questions | No | Yes | Yes |

Start practicing freeYou choose a role, a level, how many questions you want (3, 5 or 8) and how you want to answer: by voice, by voice with a self-view of your camera, or by typing. The interviewer always asks each question out loud, then listens (or reads), asks follow-ups and moves on. The level sets how hard the first questions are, and the interview adapts to how you answer. A session lasts at most 40 minutes, and you get your report as soon as it ends.
Each question is scored from 0 to 3 against a rubric for that role, and the scores are averaged into an overall result out of 100. An answer of "I don't know" counts as 0, and questions you skip are left out of the average. An AI model judges answers against the rubric, so treat scores as a useful estimate for practice, not a verdict.
Ten: Backend Engineer, Frontend Engineer, Full-Stack Engineer, DevOps Engineer, QA / Test Engineer, Data Scientist, Data Analyst, Data Engineer, Machine Learning Engineer and Product Manager. Each has 30 curated questions across 10 topics.
Yes, it is optional. Upload a PDF, Word or text file of up to 5 MB on the setup page. KickOff reads it once, keeps only a short summary (your most recent role, years of experience, a few skills and highlights) and deletes the file. The interviewer uses that summary to greet you and to ask a relevant follow-up to your introduction. It never changes how your answers are scored or which questions you get, and you can remove the summary at any time.
No. KickOff keeps a text transcript, your scores and your report, not audio or video. In video mode your camera is only shown back to you in your own browser: it is never sent to KickOff and never recorded. When you answer by voice, your live audio is sent to our speech-to-text provider to turn it into text; in text mode no audio is used. You can ask for a copy of your data or for it to be deleted by emailing [email protected]. The Privacy Policy has the details.
So that certificates mean something. KickOff notes when you leave the interview tab or your connection drops, and shows it in your report. An interview with a lot of time away does not count towards a certificate. Nothing else on your device is monitored.
For each role you can earn a Foundation and then a Professional certificate by completing several full interviews with solid scores and staying on the tab. They show practice readiness, not an employer credential. Each has a unique code, and anyone can check it on the verification page, which shows only your first name and last initial, the role, the level and the date.
The interview ends. If you had answered at least one question, you still get a report based on those answers, marked as ending early. Interviews that end early do not count towards certificates.
Yes, right now. To keep it fair for everyone you can run up to 5 interviews in any 24 hours, one at a time.
Run your first practice interview in a few minutes. No card required.
