About Ian

I'm Ian Glennon - founder of Custom Case Coach, ex-BCG consultant, and NYU Stern MBA. Over the past six years I've coached 1,000+ candidates across 95+ countries, run 5,000+ coaching sessions, and helped hundreds of candidates land offers at McKinsey, BCG, Bain, and every major consulting firm globally. I hold a 5.0 rating across 160+ reviews across Leland and PrepLounge. I built Custom Case Coach because I saw a gap: most prep resources teach candidates what to think, not how to think. Memorizing frameworks doesn't work. Interviewers can tell immediately when a candidate is pattern-matching rather than actually reasoning through a problem. CCC was built to fix that: teaching candidates to build tailored, first-principles frameworks, drive cases like real consulting projects, and communicate in a way that signals genuine capability. Not just for the interview, but for the job itself. My preparation system combines direct 1:1 coaching, a 360° recruiting course with 131 lessons and 26+ hours of content, a 300 document resource library, and structured peer practice — all built around the individual candidate, not a generic curriculum. Every candidate gets a personalized preparation plan, targeted pre-work and post-work after every session, and access to the full CCC ecosystem built over years of teaching. 95% of my fully committed candidates receive a consulting offer. Of candidates who reach an MBB interview, 67% receive an MBB offer.
