Started by talking with a recruiter, who told me the whole process would be 2.5 - 3 weeks, I ended up moving on to the first or four rounds.
First Round: Hiring Manager
Second Round: Panel interview with two of their current CSM's (customer success managers)
Third Round: One of the directors of customer success
The first three rounds went REALLY quickly. Then it was radio silence for 2.5 weeks. I reached out to the HR coordinator, who said I would be getting a response within 5 days, then 10 days later, still nothing, reached out again, and finally the recruiter sent me a canned response saying "it wasn't a mutual fit", I am totally fine with that, but the fact they moved me through three rounds of interviews, and then strung me along for 2.5 weeks, only to tell me it wasn't a "mutual fit" was a bit frustrating.
This company seems incredibly disorganized, and unprofessional. Probably a blessing in disguise that it didn't work out.
