Did the Deloitte TPM loop for a role in their technology practice. This was a lateral move for me from a Series C, so I was curious how the Big 4 interview differently. Short answer: more behavioral depth, less technical depth, more client-simulation than any product company I've interviewed at.
Round 1: recruiter screen. 30 minutes. Comp alignment, background, "why consulting vs. product." That last question is real. Have a specific answer that isn't just "I want variety." Mine was about wanting to solve problems across industries rather than going deep on one product surface. Seemed to land.
Round 2: technical assessment. I expected a systems design question. What I got was more like a scoping exercise. They described a client situation (a large organization rolling out a new ERP system, lots of stakeholders, fixed deadline) and asked me to walk through how I'd build the program plan: phases, dependencies, risks, communication cadence. The interviewer probed on how I'd handle a technical blocker in phase 2 that threatens the phase 3 deadline. No code, no architecture diagrams. Pure program management.
Round 3: behavioral panel. Two people, 90 minutes. Pure STAR throughout. Questions I remember: a time I had to manage scope when a client kept expanding requirements, a time I escalated a risk and was ignored and what happened next, how I've built relationships with technical teams who didn't trust the PM/TPM layer. That last one came up twice across two interviewers, which tells me it's a real pain point they've seen.
Round 4: senior leader interview. Principal-level. More of a conversation than an interview. They wanted to see how I thought about career trajectory and whether I could see myself growing on the consulting track. Translation: are you going to leave in 18 months.
Offer was competitive. Not FAANG total comp, but the base was $155k plus a utilization bonus structure that can add meaningfully if you're on billable client work. Just note that the variable pay really depends on how consistently you're staffed on projects.
Overall: a solid loop. The behavioral depth was the highest I've seen outside of staff-level PM roles at big tech.
