Pros
I almost didn't interview with Headspace because of some of the Glassdoor reviews. If I had followed through, I would have missed out on working for an amazing company. Headspace is known globally...but it's a start up. Remember that. It has gone from 50 to 200 employees rather quickly, so there have been & will continue to be growing pains. All I can say is that from what I've experienced, it's a company that is true to its mission: Improve the Health & Happiness of the World. If that sounds cheesy, this probably isn't the place for you because everyone is on board. This is a fantastic company with very talented people. If you're interested in an open position, don't let this site deter you from applying.
Cons
I don't necessarily think you need to have prior experience using Headspace to work here...but let's be real, this is a very purpose-driven company. You should probably download the app & try meditation before you apply.
