Reddit Program / Project Manager Interview Questions

1.Tell me about a project you managed where sudden growth or a traffic spike forced you to rethink your execution plan mid-flight. What changed and how did you keep things moving?

2.Tell me about a time you had to coordinate a major infrastructure or capacity project across multiple teams under a hard deadline. What broke down and how did you hold it together?

3.Walk me through a time a product or feature decision you were shepherding would have hurt a specific user community if it shipped as planned. What did you do about it?

4.Tell me about a time you were managing a product or system and discovered it was being abused or gamed in a way nobody anticipated. How did you respond?

5.Describe a time when the 'right' process was going to take too long and you shipped something scrappy instead. What did you cut corners on, and would you make the same call again?

6.Tell me about a time you fought for a feature or change that gave users more control over their own experience — especially one where internal stakeholders were skeptical.

7.Rough estimate: how many active subreddits do you think Reddit has, and what percentage of them do you think are genuinely active — say, at least one post per week? Walk me through how you get there.

8.Reddit's weekly active user count dropped 8% in a specific region last month. No major outages, no obvious product changes. How do you approach diagnosing what happened?

9.Reddit is considering investing in a self-serve program to help small and mid-sized advertisers ramp up on the Ads platform faster. You're asked to build a business case for it. What data would you pull together, and what does your framework look like?

10.You're managing a program to improve Reddit's search relevance, and after six weeks of work, engagement with search results is up 12% but comment contributions from search-entry users are down 7%. How do you interpret that and what do you do next?

11.Estimate the revenue impact to Reddit if the average CPM on the Ads platform dropped by $2 across all inventory. Walk me through the math.

12.You've been asked to figure out whether Reddit should invest in building native translation features to accelerate international growth, or continue relying on third-party machine translation. How do you frame the decision and what would you need to know?

13.How do you structure a program roadmap when you're managing dependencies across three or more teams — and how do you keep it from becoming a wall of Gantt chart nobody reads?

14.Walk me through how you measure whether a program you own is actually on track — not just on schedule, but delivering real value. What's your go-to set of health metrics?

15.You're running a program with a firm external deadline — say, an ads product feature that needs to be live before a major Q4 advertiser campaign window. Three weeks out, two of your five workstreams are behind. How do you decide what to cut vs. what to protect?

16.Tell me how you'd run a post-mortem for a program that missed its deadline by four weeks. Not just the ceremony — walk me through your actual process for making it actionable.

17.You're the DRI on a program that spans Reddit's Safety team, the Ads team, and a third-party data partner. Each group has a different reporting structure and a different definition of 'done.' How do you establish shared success criteria before work starts, and what happens when they drift?

18.A senior engineer tells you that the technical approach your program is built around will accumulate significant debt that will slow down the next two quarters of work. Product wants to hit the current deadline anyway. How do you handle this, and what's your role as the PgM in that decision?

19.You're onboarding to a new program and realize the status doc the team has been sharing with leadership is consistently more optimistic than what engineers are telling you in 1-on-1s. How do you handle that gap?

20.A community manager flags that a new moderation tooling feature your team shipped last week is being used in a way that's causing false positives — legitimate posts are getting removed in several large subreddits. Engineering says it's working as designed. What do you do?

21.You've just been handed ownership of a program that three previous PgMs touched and nobody finished. Stakeholders are fatigued, documentation is scattered, and nobody agrees on what 'done' looks like. How do you get it moving without losing the room in the first two weeks?

22.Reddit is preparing to launch a new ad targeting feature for a major brand advertiser partnership. Two days before go-live, a trust and safety review flags a potential misuse vector — malicious actors could use the same mechanism to micro-target vulnerable user groups. Legal says it's not a compliance blocker. What do you do?

23.You're running a cross-functional program and discover mid-execution that one team's work is technically correct but solving a slightly different problem than everyone else is solving — the misalignment has been baked in for six weeks. The team lead insists they were following the original spec. How do you course-correct without derailing the program or the relationship?

24.Leadership asks you to stand up a new program to accelerate Reddit's international growth — you have a loose mandate, no dedicated headcount, and three teams who've been told to 'support' you but have their own roadmaps. Ninety days from now, how does success look, and how do you get there?

25.Tell me about a time you needed a team to prioritize your program's work, but you had no authority over their roadmap. How did you make it happen?

26.Describe a time you had to give a stakeholder bad news — a slipped date, a cut scope, or a failed assumption — and they didn't take it well. How did you handle the conversation?

27.You're running a program that needs sign-off from both a revenue-focused team and a user-trust team, and their approval criteria are genuinely in conflict. Neither will budge first. How do you break the deadlock?

28.Tell me about a time you managed a stakeholder who kept expanding scope mid-program — not maliciously, but because they were genuinely excited about what the work could become. How did you handle that without killing the momentum?

29.Tell me about the most senior stakeholder you've had to tell no. What was the ask, how did you frame the pushback, and what happened to the relationship afterward?

30.You're coordinating a program across three partner teams and you realize one of them has been consistently underrepresented in decision-making — their feedback shows up late, they're not in the key syncs, and the program is heading toward a launch that works for everyone except them. What do you do?
