Not every team is created equal at Facebook. I'm a Product Support Specialist at Facebook working under the Global Shared Services department. Unfortunately, the role that was stated in the JD is not the role that I am in.
I was told the Product Support role would be a precursor to Product Management and that you will be spending a lot of time strategizing and helping product teams with their product roadmaps. A couple weeks in, and I soon realized that this role is purely operational and SLA based. We manned bug reports on a daily basis. Everything was numbers driven, but not in the right way. We were encouraged to analyze the tickets to find ways to improve SLA.
Leadership is quite weak. They only listen to our goals and aspirations but neither help us or nor point us to the right direction. Most of the team don't plan to stay for long. Everyone seems to have a plan B or to be using this role as a springboard to another one within Facebook.
Although I hear great things from other teams, this one is not it.
