Interview Coaching
Valerian is the real thing - a recent ex-McKinsey EM from the ME office who conducted 100+ interviews, and it shows in how precisely he diagnoses you.
We ran a full case end-to-end and the feedback was the most actionable I've had. He doesn't just say what was weak - he shows you the ladder from what's wrong to what to do to how you'd actually implement it, and explains that the last level is what separates a good answer from a great one. He also corrected my structure at exactly the right altitude: my framework was fine, but he showed why a different logic fit that specific case better, and had me rebuild it live.
You're graded against the real McKinsey scoring dimensions, with written question-by-question feedback afterwards - so you leave knowing precisely where you stand. His calibration is honest: he tells you clearly what passes and what doesn't.
Highly recommended.
