How does the PM role vary across teams and companies?

The expectations on Product Managers are so different and it’s important that you really take the time to understand what’s your unique skill set and what you really enjoy doing, so that you can match that with the company’s expectations. 

Some PMs may focus more on faster product iterations (e.g. Growth hacking), others may well work on very large and complex technical problems (e.g. my work at Google Health).
