You've just launched Facebook Jobs, a marketplace for employees and employers. Job listings are up 20%, but employer response time for applicants is down 20%. How would you approach this?

This situation requires a multi-pronged approach. First, I'd investigate the data to understand the trend: is the response time decrease gradual or sudden, and does it correlate with specific employer segments or job types?

Next, I'd analyze the user experience for employers. Are they overwhelmed with applications due to the 20% increase in listings? Is the platform providing them with efficient tools to manage and respond to applicants? We might need to introduce features like automated responses, applicant filtering, or batch communication tools.

Simultaneously, I'd explore ways to incentivize faster employer responses. This could involve highlighting employers with quick response times, offering badges, or providing educational resources on the benefits of timely communication.

Finally, I'd consider if the definition of 'response time' needs refinement to account for the increased volume, or if we need to set clearer expectations for employers on the platform.
