Sharing 2 interview questions I got for Growth PM at FB:
*How would you optimize email notifications after users are tagged in photos? Follow up questions on how to improve engagement. *
How would you convert Facebook users to Instagram through the Facebook app? Provide concrete ideas and how to measure success.
I actually practiced the first question when I was preparing and fortunately got it during the real interview. The key is to practice as many questions as you can (even just thinking through your approach) before formally interviewing. You’ll get the hang of it or even see similar questions.
