Interview Process Overview

The interview process for the Product Manager, Instagram Search role was structured into multiple stages, each designed to assess my ability to drive product strategy, work cross-functionally, and think analytically about Instagram’s search and discovery features.

1. Initial Screening with Recruiter

The first step was an introductory call with the recruiter. This conversation was focused on my background and interest in the position. The recruiter shared details about the team structure, the scope of the role, and Instagram’s focus on improving search, discovery, and content relevance.

  Example Question: “How would you improve Instagram’s search ranking algorithm to ensure users find relevant content quickly? What factors would you consider (e.g., recency, engagement, user preferences)?”

• Data-driven decision making: I was given a scenario involving A/B testing to measure the impact of a proposed change in search functionality. The interviewer asked me how I would set up the experiment, define success metrics, and interpret the results.
  Example Question: “You’re testing a new search feature that ranks results based on user interest. How would you structure an A/B test to evaluate its effectiveness?”

• Metrics and KPIs: A large part of the interview focused on defining success for search-related features. I was asked to identify key performance indicators (KPIs) for measuring the effectiveness of search improvements and how I would track user engagement with new features.
  Example Question: “What metrics would you track to measure the success of a feature that improves the discoverability of content through Instagram search?“
