Behavioral Questions (6)
1.Tell me about a time a quieter person on your team had an idea or concern that wasn't getting airtime. How did you bring it forward, and what changed because of it?
easy~3 minWhat interviewers look for
- Candidate noticed the gap proactively — didn't wait for the person to advocate for themselves or for a manager to intervene
- Used a concrete mechanism to amplify the voice: a 1:1 before the meeting, a written async summary in a Slack channel, a direct call-out in the room — not just vague 'I made space for them'
- Credits the teammate by name or role when describing the outcome, reflecting Slack's Solidarity value — sharing credit rather than absorbing it
- Reflects on why that perspective was being missed structurally — seniority dynamics, meeting format, timezone — and whether they changed anything going forward
Likely follow-ups
- What made you notice this person specifically — was there a signal you'd missed earlier that made you more tuned in?
- If that teammate had disagreed with the ultimate decision, how would you have handled it?
Company context
Slack's Inclusive Collaboration principle explicitly calls out making sure quieter voices are heard — it's listed as a named leadership principle, not just a cultural aspiration. For a Program Manager role at Slack, where PMs, engineers, designers, and cross-functional stakeholders regularly interact across channels and async formats, the ability to create equitable airtime in distributed conversations is operationally critical. Slack's own product (channels, threads, Workflow Builder forms) is built partly to democratize input — so PMs who model that behavior in their programs are directly aligned with how Slack thinks about good work.
2.Describe a time you gave feedback on someone's work — a doc, a plan, a spec — and the feedback was harder to deliver than just flagging a typo. What did you say, and how did you frame it?
easy~3 minWhat interviewers look for
- Feedback was substantive — challenged a decision, a framing, or a scope call — not purely stylistic or corrective
- Candidate describes the specific language or framing they used to make the feedback constructive rather than critical — Slack's 'Code Review with Care' principle is as much about tone as technical accuracy
- Outcome is concrete: the person updated their work, they pushed back and the candidate updated their view, or a third path emerged — not just 'they appreciated it'
- Candidate reflects on what made the feedback land — relationship, timing, async vs. sync format — showing awareness of communication craft
Likely follow-ups
- How did you decide whether to give that feedback async — say, in a Slack thread or doc comment — versus pulling the person aside?
- Has there been a time you got feedback on how you give feedback? What did you change?
Company context
Slack's 'Code Review with Care' principle — originally articulated for engineering but deeply embedded in the broader culture — holds that feedback should be technically sharp and respectfully delivered. For a Program Manager at Slack, this manifests in how they review project plans, product specs, or partner team deliverables. Slack's culture explicitly rejects feedback that is either toothless (no real substance) or blunt without care (technically right, interpersonally damaging). The company's async-first communication norms mean written feedback is often the primary channel, raising the stakes for craftsmanship in how feedback is worded.
3.Tell me about a time customer feedback — from a user, a support ticket, a sales call, anything — changed what you actually built or prioritized. What did you hear, and what did you do with it?
medium~4 minWhat interviewers look for
- Candidate personally engaged with the customer signal — didn't just receive a second-hand summary from a PM or account team — showing direct customer empathy rather than filtered empathy
- The signal changed something concrete: a feature was scoped differently, a launch was delayed, a priority was reordered — not just logged and noted
- Candidate shows they weighed the customer signal against competing constraints (roadmap, engineering capacity, strategic bets) and made a deliberate trade-off — not just 'the customer said it so we did it'
- Connects the customer signal to a user population or segment, not just one anecdote — showing scale thinking relevant to Slack's enterprise and SMB customer base
Likely follow-ups
- How did you decide this one signal was worth acting on versus treating it as an outlier?
- Did the team push back on the reprioritization? How did you make the case?
Company context
Slack's Customer Empathy leadership principle expects engineers and PMs to actually use the product, seek customer signals directly, and let those signals influence technical and product trade-offs — not just defer to PMs as the 'voice of the customer.' For a Program Manager at Slack, this is especially pointed: Slack serves a huge range of customers from individual users to large enterprises using Slack Connect for cross-company collaboration, and the PM is often the person who has to translate customer reality into program priorities. Slack's Craftsmanship value also reinforces this — caring about how the product lands for real people, not just whether it shipped.
4.Walk me through a disagreement you had with a partner team — engineering, design, sales, whoever — where you genuinely thought they were wrong. How did it resolve, and do you think you got to the right answer?
medium~4 min5.Tell me about a cross-functional project where someone's input was being systematically overlooked — not because they were wrong, but because of how the team was structured or who had the loudest voice. What did you do about it?
hard~5 min6.Tell me about a time you received feedback on a deliverable — a roadmap, a project plan, a stakeholder update — that fundamentally changed how you thought about the work, not just how you polished it. What was the feedback and what did you actually change?

easy~3 min9.You're asked to estimate the annual cost to Slack of poor meeting culture — people scheduling calls instead of using Huddles or async channels. How would you frame the problem and what's your rough number?
medium~4 min10.A Slack Workflow Builder automation that an enterprise customer relies on for their daily stand-up process stops triggering correctly after a Slack platform update. The customer contacts you directly. How do you manage the next 24 hours?
medium~4 min11.Slack is considering whether to invest in a self-serve onboarding program for mid-market customers — companies between 100 and 1,000 seats — to reduce reliance on CSMs for basic onboarding. How would you structure the analysis to decide if this is worth building?
hard~5 min12.Slack's Huddles feature has strong engagement among engineering teams but low adoption in sales and customer success orgs. You're asked to run a 90-day program to close that gap. How do you design the program, and how do you measure whether it worked?

Situational Questions (6)
19.You're coordinating a Slack Connect rollout for a new enterprise customer and their IT admin goes dark three days before the scheduled go-live. No response to messages, no handoff. What do you do?
easy~3 min20.You've just been handed a project that has three executive sponsors who all think they're the primary decision-maker. No one has explicitly resolved that ambiguity. How do you handle it before it becomes a crisis?
easy~3 min21.You're managing a cross-functional program and halfway through you realize the success metrics everyone agreed to at kickoff no longer reflect what the business actually needs.

medium~4 min22.You're running a high-visibility internal program and a senior engineer on the team starts consistently missing deadlines without explanation, causing downstream slips. You don't have direct authority over this person. What's your move?
medium~4 min23.You're three weeks from launching a major enterprise feature and a customer advisory board session — which ran after the build started — surfaces that your core assumption about how customers will use the feature is probably wrong. Changing direction now would blow the timeline. What do you do?
hard~5 min24.You're the program manager on a Salesforce-Slack integration initiative and you discover that two separate teams — one on the Slack side, one on the Salesforce side — have been building overlapping solutions to the same problem for six weeks without knowing about each other.
