Run full consulting cases and get a scored debrief after each one, so you know exactly what to fix before your interview.
Free cases. No credit card.
Start with a full case to see where you stand, then fix your weak spots with drills.
Work a full case step by step with prompts, then see how a strong candidate structured the same problem.
Short timed reps on one skill at a time: math, structure, brainstorming, exhibits, synthesis.
The screening formats firms run before interviews, rebuilt with their real timing and constraints.
Run a live spoken interview against an AI interviewer and answer out loud, under pressure.
Run real cases, get a detailed debrief on every answer, and drill what you got wrong.
Guided mode prompts you through a full case one step at a time. Voice mode takes the prompts away and makes you answer out loud.
Every answer returns seven weighted dimensions separately, quoting your own words, and names the one to correct first.
Timed reps on arithmetic, exhibits, structuring, brainstorming, synthesis and sizing. One skill at a time, so a weakness has somewhere to show.
Learning mode covers the method first: what a structure is for, how an exhibit is read, which arithmetic shortcuts are worth having.
Pick your target firm and level to see what the offer pays, and what your prep costs.

“I've applied to consulting roles both with and without protocol, and the difference was huge. This time I got the job (M&A at McKinsey), and I walked into the interviews feeling far better prepared and confident.”
Kim C.McKinseyI used protocol career to prepare for my EY interviews and it made a real difference.
The voice case was the most useful part for me. Answering out loud against the AI interviewer is much closer to the real thing than reading cases or practicing in your head. By the time the interview came, I was over-prepared. The actual case felt easier than what I had been doing on protocol, so nothing caught me off guard.
The hiring likelihood score also helped a lot. It gave me a clear read on where I stood and when I was ready, instead of guessing. I walked in on the day knowing my level.
If you're preparing for consulting interviews, I'd recommend it.
Juan A.EYOn top of being a great tool, they have a support team that really went out of their way to help me. Between the two, I felt fully prepared and supported.
Lisa C.PwCI used Protocol career to prepare for my interviews and landed a Manager position at Deloitte. The product is well structured and clearly built to give you every chance of succeeding. You can tell it was designed by senior consultants who have been through the process themselves. The continuous scoring was the most useful part for me: instead of guessing whether I was getting better, I could see where I was progressing and where I still had work to do. I'd recommend it to anyone preparing seriously for consulting interviews.

Protocol helped me walk into my interviews prepared and confident. I went through the whole recruiting process calmly, without any bad surprises.
Sam T.BCGSince I started using it, I feel a lot sharper. My structure has improved a lot, especially under pressure, and I now do much better on cases.
Elijah L.BainProtocol is really well designed for making fast progress. No fluff, just what you need to work on. It puts every chance on your side to stand out and get the job. It's what made the difference for me in landing the Business Analyst role.
Larry J.McKinseyI had my interview coming up at EY and was looking for anything that could help me prepare, mostly YouTube videos. I was lucky to come across this. It really helped me get ready and feel confident going into the interview. I ended up landing the role I was preparing for.
Joshua A.EYLanded my target role at KPMG after preparing with Protocol Career. Having one well-designed way to prep beats watching dozens of YouTube videos and reading blogs full of outdated cases. Money well spent.

One posting publishes real dates: 39 days from application, 16 from confirmation. Case interview prep plans from there, forty hours against what firms assess.
Read the guideFor structure, math, exhibits and synthesis, yes. Those are mechanical and improve with graded reps. A coach still reads you better than any scoring engine, and will tell you the thing nobody else will. If you can afford both, the coach is worth more once the mechanics are solid.
A few questions, one real case, and a score on the dimensions firms publish. No account, no card. Or read a case first, if you would rather see the exercise before you are measured on it.
