6 experiences Difficulty 3.7/5 Technology / Social Media

Engineering Manager (Ads / Monetization)

onsite · Difficulty 4/5

Candidates report an initial recruiter screen focused on management scope, team size, and domain alignment with ads delivery, measurement, ranking, or advertiser tooling, often followed by a short hiring manager call. The core loop frequently includes multiple interviews split across people leadership, cross-functional collaboration, and technical depth, with an emphasis on how managers drive execution in systems that impact revenue and advertiser outcomes. A technical round is commonly framed around architecture and decision-making rather than pure coding, covering tradeoffs in reliability, latency, experimentation, and data quality for ads systems. Another stage typically centers on leadership scenarios like performance management, hiring, leveling, and creating clarity across engineering, product, data science, and sales stakeholders. Final interviews often include a broader values and culture conversation and occasionally a presentation of a prior initiative or a proposal for improving a component of the ads stack, with overall timelines commonly taking several weeks from first screen to offer depending on panel scheduling.

  • How would you design and evolve an ad ranking and delivery system to balance relevance, revenue, and user experience on a discovery platform like Pinterest?
  • Describe a time your team missed a key milestone. What did you change in planning, execution, or stakeholder management afterward?
  • When product and sales stakeholders push for faster feature delivery but the ads platform has reliability risks, how do you make the tradeoff decision and communicate it?
  • What signals would you monitor to detect degradation in ads performance or measurement accuracy, and how would you run the incident response?
  • How do you build an inclusive, healthy team culture while maintaining a high bar for engineering quality and operational excellence?

Client Partner (Advertising Sales)

virtual · Difficulty 3/5

Candidates report starting with a recruiter screen focused on interest in Pinterest’s advertising business, transferable sales experience, and territory or vertical fit, typically scheduled within one to two weeks of applying. The next stage is commonly a hiring manager interview that probes consultative selling fundamentals, client communication, and how candidates would position Pinterest solutions such as promoted Pins and performance-oriented campaigns. Many processes then include a short case or pitch exercise, often framed around a mock advertiser and requiring a simple plan covering objectives, audience, measurement, and creative strategy suited to the Pinterest format. A panel stage with cross-functional partners is also typical, where interviewers test collaboration with measurement, creative strategy, or account operations and how candidates handle objections and budget constraints. Final steps often include reference checks and a team matching conversation, with overall timelines commonly spanning several weeks depending on headcount and interview panel availability.

  • Walk through how you would pitch Pinterest to a performance marketer who currently spends on Meta and TikTok and is skeptical about incremental value.
  • Describe a time you had to influence a client or internal partner without formal authority. What was the outcome?
  • Given a mid-market retailer launching a seasonal campaign, what objectives would you recommend on Pinterest and what metrics would you use to judge success?
  • How would you troubleshoot a client reporting weaker ROAS week-over-week on Pinterest, assuming creative and budgets stayed similar?
  • Pinterest positions itself as a more positive place online. How would you reflect that in the way you advise on creative and targeting?
