Facebook Product Manager Interview Questions
The Facebook PM interview includes three components:
- Product sense
- Execution interview questions
- Leadership and Drive
Product sense (interview questions)
- How would you design Facebook Events 2.0?

- How would you prioritize the different things you want to work on?
- Weekly active users (WAU) for Facebook’s iPhone dropped. What happened?
Leadership and drive
Sample questions for testing leadership and drive include:
- Give me an example of when you disagreed with an engineer. And tell me how you convinced him or her?
- What’s a self-development area that needs improvement?
- What’s your favorite project where you played a leadership role?
- What’s a technology trend that you’re excited about?
Amazon Product Manager Interview Questions
Amazon tests the product manager candidates in the following areas:
- Negotiating skills/ability to influence other
- Thinking Big
- Deliver results

Negotiating skills questions
In this area expect questions like:

Deliver results (Behavioral questions)

- When was the last time you had an idea to improve the way things work? Tell me more, was this idea implemented? Why or why not?
- Tell me an example of a situation where you disagreed with the decision of a manager or higher-ranked individual. How did this play out and explain to me, what was the final decision?
- Choose a company that you believe provides a world-class customer experience, and tell me why you choose exactly that company, what do they do well?
- Did you ever have a situation in which you communicated a very complicated situation to a group of people that were completely unfamiliar with the topic? Explain to me, what approach did you take in this situation?
