Case library FAQ

Are these case interviews really free?

Every case here is free to open and read in full. A free Road to Offer account includes your first full case with AI feedback on structure, math, and synthesis; further reps are part of Pro.

What is the difference between voice and guided mode?

Voice mode runs a live spoken mock interview: the AI interviewer asks questions and you answer out loud, like a real case interview. Guided mode is typed, with hints and a saved debrief, and is the easier place to start if you are new to casing.

Which case should I start with?

Start with an easy profitability case, since profitability is the most common case type at McKinsey, BCG, and Bain. Filter by difficulty above, run it in guided mode, then re-run the same case in voice mode once the structure feels natural.

Do the cases match real MBB interviews?

Each case is written in the style of a specific firm (McKinsey, BCG, or Bain) with the exhibits, quant steps, and synthesis expectations those firms use, so the reps transfer directly to real interview rounds.
