I got in touch with a recruiter who set me up with a 20 min phone screen followed by a 30-45min in depth background interview with the department director the following week. Process started off fine, they were responsive and friendly - but after my second interview, both the recruiter and department director ghosted me, and didn't reply to email follow ups I sent after 2-3 weeks of waiting - extremely rude and unprofessional, I think their recruiting department isn't too well coordinated. No official rejection or courtesy reply. Otherwise, seems like a cool company in an interesting space.

Initial conversation with head of recruiting, then several phone screens followed by 'superday' of back to back zoom interviews with junior and senior members of team, as well as different team heads.
