Customer case studies
Eight real customers. Every practice session scored. Nothing polished after the fact.
They knew their experience cold. Until they had to say it out loud.
Every candidate here had the background for the job. What they didn’t have was proof that their answers would hold up in the room. Each story follows one customer, from an ER nurse to an Amazon operations manager to a process control engineer, through the sessions where Rev caught what a friend would have let slide.
Read together, a few patterns stand out.
- The most common problem wasn’t missing experience. Seven of the eight candidates were caught answering a different question than the one asked, skipping part of a prompt, or sidestepping a behavioral question.
- “We” hides you. Four of the eight were told to say “I” instead of “we,” and a fifth was told to say plainly that they built the financial models themselves.
- Progress was never a straight line. Every candidate had at least one session that scored 0.8 points or more below the one before it. The median was 13.5 scored sessions.
One candidate told us they advanced to the next round. The other seven haven’t reported an outcome, and each page says so.
