Behavioral Questions (6)

  1. 1.Tell me about a project that was clearly broken — missed deadlines, unclear ownership, confused stakeholders — that nobody else was stepping up to fix. How did you take it on?

    easy~3 min

    What interviewers look for

    • Candidate proactively identified the problem and self-assigned ownership without being asked or given formal authority
    • Candidate diagnosed root causes (not just symptoms) and built a concrete plan to address them — stakeholder map, milestones, or accountability structure
    • Candidate reflects on what they'd do differently or what the situation taught them about how ownership works cross-functionally

    Likely follow-ups

    • Who else could have stepped in — and why didn't they? How did you navigate that dynamic?
    • What was the moment you realized this was yours to fix, and what was the first concrete action you took in the next 24 hours?

    Company context

    Brex's 'Be an Owner' principle explicitly expects employees to surface problems, propose solutions, and drive them to closure without waiting for permission or escalating upward. For a mid-level PM at Brex, who often works across engineering, finance, and product teams on fast-moving spend management features, the ability to self-assign ownership of ambiguous or dropped-ball situations is table stakes — not a differentiator. This question tests whether ownership is a genuine behavior or just a talking point.

  2. 2.Tell me about a memo, project brief, or written proposal you wrote that actually changed what a team decided to do. What was in it, and how did it land?

    easy~3 min

    What interviewers look for

    • Candidate can articulate the specific argument or structure of the document — what problem it named, what options it considered, and what it recommended
    • The document changed a real decision or direction — not just informed one — and the candidate can describe the before/after state
    • Candidate shows intentionality about audience and format — why written, why structured that way, how they anticipated objections

    Likely follow-ups

    • Walk me through the structure — what were the first two sections and why did you order it that way?
    • Who pushed back on it, and how did you respond in writing versus in person?

    Company context

    Brex runs a memo culture where strategy docs, OKRs, and key decisions are written, shared, and debated openly. PMs at Brex are expected to think in writing — not just to document decisions but to shape them. A mid-level PM who can only communicate synchronously will struggle to operate effectively in this environment. This question probes whether the candidate has genuine fluency with written persuasion as a primary tool, not a backup.

  3. 3.Tell me about a time you pushed back on a fast-fix solution and argued for doing something the harder, more durable way. How did you make the case, and did it hold up?

    medium~4 min

    What interviewers look for

    • Candidate clearly articulates the trade-off they were navigating — what the shortcut would have cost long-term versus what the harder path required in the short term
    • Candidate made a structured, evidence-based case for the long-term approach — not just a gut feeling — and influenced the decision
    • Candidate can reflect on the outcome: did the long-term call prove right, and what would they do differently in how they made the argument?

    Likely follow-ups

    • What was the pressure you were pushing against — timeline, stakeholder expectations, or both?
    • If the team had overruled you and gone with the shortcut, what would you have done?

    Company context

    Brex operates in a regulated financial domain where shortcuts in process, tooling, or program design can compound into compliance exposure, customer trust failures, or technical debt that slows future products like Brex Empower or Brex Business Account. The 'Engineer for the Long Term' principle — though named for engineers — applies equally to PMs, who constantly face pressure to cut corners on process rigor, documentation, or cross-team alignment in order to ship faster. This question tests whether the candidate can hold a long-term standard under real pressure.

  4. 4.Tell me about a time you had to share bad news — a missed deadline, a project going sideways, or a decision that would upset stakeholders — before anyone asked you to. What did you say, and how did people react?

    medium~4 min

  5. 5.You're the PM on a cross-functional initiative and two engineering leads from different teams have a hard disagreement about scope that's blocking progress — and neither reports to you. How do you move it forward?

    hard~5 min

  6. 6.Tell me about a project brief or program charter you wrote that other teams used to make real decisions — not just to stay informed. What did you put in it that made it actually useful?

    hard~5 min

Problem Solving Questions (6)

  1. 7.Estimate how many Brex corporate card transactions happen on a typical weekday. Walk me through your assumptions.

    easy~3 min

  2. 8.A key metric — let's say the percentage of Brex expense reports submitted within 30 days of a transaction — drops 8% month-over-month with no obvious product changes. How do you diagnose it?

    easy~4 min

  3. 9.Brex wants to roll out a new automated spend policy feature to its enterprise customer base over 90 days. How would you structure the rollout plan, and what are the biggest risks you'd plan for?

    medium~4 min

  4. 10.You're the program manager for Brex's annual planning cycle. Three product teams have submitted roadmap requests that together require 40% more engineering capacity than exists. How do you facilitate getting to a plan that leadership can commit to?

    medium~5 min

  5. 11.Brex is deciding whether to build a new automated reimbursement flow in-house or integrate with a third-party vendor. You're asked to run the evaluation and make a recommendation to leadership. How do you structure the analysis, and what does your recommendation memo look like?

    hard~5 min

  6. 12.You're running a program to migrate Brex's mid-market customers to a new expense management experience. Halfway through the migration, customer success reports a surge in support tickets and one customer has threatened to churn. Engineering says the product is working as designed. What do you do?

    hard~5 min

Role Knowledge Questions (6)

  1. 13.Walk me through how you track a program's health week-over-week. What metrics do you actually look at, and when do you escalate?

    easy~3 min

  2. 14.A launch you're coordinating has five workstreams and three of them are behind. How do you decide which ones get your time and which ones don't?

    easy~3 min

  3. 15.Tell me about a time you drove alignment on a program timeline when different teams had genuinely different constraints — one needed more time, one needed to ship faster. How did you land on a plan everyone could commit to?

    medium~4 min

  4. 16.You're managing a multi-team program and you realize mid-execution that a key assumption in the original plan is wrong — not a small tweak, but a change that affects scope, timeline, and resourcing. How do you handle it?

    medium~4 min

  5. 17.Imagine you're the program manager for a new Brex Empower feature that involves product, engineering, compliance, legal, and a third-party integration partner. How do you structure your dependency tracking, and what breaks first when something slips?

    hard~5 min

  6. 18.You're six weeks into a 16-week program and your velocity data shows you'll finish in 22 weeks, not 16. The launch date has an enterprise customer commitment attached. What do you do in the next 48 hours?

    hard~5 min

Situational Questions (6)

  1. 19.You're coordinating a product launch and realize the runbook you inherited from the last PM has a gap — nobody owns post-launch monitoring for the first 48 hours. How do you handle it?

    easy~2 min

  2. 20.You're running your weekly program sync and an engineering lead casually mentions their team is picking up a 'small' infrastructure change that wasn't in the original scope. It sounds minor, but you don't fully understand the technical implications. What do you do?

    easy~3 min

  3. 21.You're managing a program with a hard external deadline — a contract commitment to an enterprise customer. Midway through, you learn that a key vendor integration will be delayed by three weeks due to something outside anyone's control. The deadline can't move. What's your plan?

    medium~4 min

  4. 22.You're the program manager for a compliance-required change that must ship by a regulatory deadline. Product wants to add a feature enhancement to the same release to maximize the customer impact. Engineering says doing both safely is possible but tight. What do you recommend, and how do you get alignment?

    medium~4 min

  5. 23.You're running a high-visibility program and two weeks before launch, a mid-level engineer on one of the workstreams tells you privately that their lead has been signing off on testing that hasn't actually been completed. You can't verify it yourself. What do you do?

    hard~5 min

  6. 24.Your program spans three teams and is two weeks from launch when a senior stakeholder from outside the program — a VP you don't report to — sends a message in the company-wide Slack channel publicly questioning the approach and suggesting a scope change. The rest of the program team sees it. How do you respond?

    hard~5 min

Stakeholder Questions (6)

  1. 25.Tell me about a time you had to get a team to care about your program when it wasn't their top priority. What did you actually do to move them?

    easy~3 min

  2. 26.Walk me through a time you had to bring a skeptical executive into alignment on a program they hadn't bought into. How did you approach that conversation?

    easy~3 min

  3. 27.Tell me about a time you were the person in the room representing a project to a customer or external partner and the conversation went sideways — they pushed back hard on something you couldn't change. How did you handle it?

    medium~4 min

  4. 28.You need sign-off from three different teams to hit a milestone, but each team's lead is telling you they're waiting on one of the others first. Nobody is moving. How do you break that?

    medium~4 min

  5. 29.Tell me about the most senior stakeholder you had to tell 'no' or 'not yet' to. How did you frame it, and what happened?

    hard~5 min

  6. 30.You're running a program where sales has committed to a feature with a key enterprise customer and the product team says what was promised isn't exactly what's being built. Sales won't budge on the customer commitment. Product won't expand scope. How do you resolve it?

    hard~5 min
