I applied through a recruiter. The process took 4 weeks.

They put me through over five rounds of interviews (take home assignment, multiple lengthy video calls), and asked for references to be checked after "successfully" making it through the onsite process. Like other posters have noted, during the interviews they ask for your past managers' names, how they would rate you, and strongly suggest you use them as references (including your current boss!).

After a positive reference check (emphasis theirs), they said they wouldn't be moving forward with an offer due to revisiting the team's needs / other vague fit answers. This is the worst, most unprofessional, disrespectful interview process I've ever been through in my life.

This company is totally cool with you jeopardizing your employment for nothing in return. It seems clueless at best, and totally unethical / borderline illegal at worst. Run far away from Hinge Health!

How would your boss rate your performance?

Please provide them as a reference.
