did the brex tpm loop in february 2026. left with an offer, writing this up because the tpm-specific content out there is thin.
the loop (5 rounds): recruiter screen (30 min) hiring manager intro (45 min) technical depth round cross-functional leadership round values + culture
hiring manager intro: not a screening call, more of a direction-setting conversation. they asked what drew me to tpm specifically at a fintech vs a pure-tech company. have a real answer for this. "brex's scale and complexity" is not a real answer. what does brex actually do (corporate cards, expense management, business banking) and why does that problem space interest you from a program management angle.
technical depth round: held by a staff engineer. they walked me through a hypothetical: a multi-quarter migration project from a monolith to services. how do i structure the program, sequence dependencies, handle rollback scenarios. they pushed when my sequencing felt too optimistic. the bar is: you need to understand enough engineering to have credible conversations with your tech lead, not write the code.
cross-functional leadership round: two interviewers, a pm and an eng manager. tell me about a time a program went sideways and you had to make a hard call. then: how do you handle a situation where pm and eng have different definitions of done. very much STAR format. bring examples with numbers (timelines, team size, scope in weeks).
values round: lighter. asked about how i handle ambiguity, what i do when the roadmap shifts underneath a program i'm running. brex moves fast and they want to know you don't need a fully mapped spec before you start.
a few tactical notes: brex tpm is closer to eng-side than biz-side. they want you tracking technical risk, not just timeline risk. they use jira and notion internally, not internal custom tools. no gotchas there. ask your recruiter whether your loop will include a written case or a presentation. mine didn't but i've heard some loops do.
the process felt well-structured. debrief came back in 5 business days.
