Pros
Company really do care about work life balance and people. You are not penalized for having a good work life balance and great benefits. One of rare companies where managers will actively ask have you taken a vacation to relax.
Cons
HR is absolutely terrible. Great intentions, horrible executions, underwhelming HR talent, so don't be taken in by illusion of it. HR butcher many things including career development, compensations, interview experience, and so forth. Spotify is NOT the place to come to grow your career for majority of people. Only few can actively grow their career here. Spotify is place to come if you want a great work life balance at cost of non-existent career development except for Engineers and Product Managers. Hell, even in people who are in accountable to work on career development frameworks such as HRBPs don't have career framework for themselves.
