straightforward, easy. Asked me pretty standard questions and the recruiting process itself took about 3 weeks. Talked to 4 PMs and the recruiter was consistently in touch and very reachable.
I applied through a recruiter. The process took 3 weeks. I interviewed at Groupon (Palo Alto, CA) in Mar 2015
Interview
The interview process was quite standard for PM interviews. Mostly asked about how to Improve Groupon and talked about favorite mobile and web products and how you would improve those. There some questions related to metrics and what are the important metrics a PM should measure.
Recruiter Screen, first-round single interview, final round four interviews.
General product management questions, behavioral questions, understand how Groupon operates, how you work with others.
My interviews were quickly scheduled and it took about a week to hear back after the final round.
