Simple interview process. Applied, the recruiter emailed me back to schedule a call, and then I received a take home assignment to show how I would answer actual customer questions. I was told the team loved my answers and then moved forward to the next interview process to talk to a senior team member on the CS team. Note, I did find this somewhat strange as any company that tends to utilize members of their company who are not peoples ops, recruiters, HR, management, or leadership do not tend to give good interview experiences, but I digress.
During the interview, she asked me a lot about my experience and it was more of a conversation than it was an interview. Then we did a live portion where she gave me a scenario and I answered the questions with no help from their Zendesk help center or her, as they were trying to call upon your experience to see how you'd answer.
When I finished, I was told the recruiter would get back to me. When he finally did which was almost a week later, I, too (like someone else who's given their interview experience here), was given a very vague and contradictory reason as to why they would not move forward with the offer as they had found someone else more suited for the team's needs at the time...mind you, the position is still open and accepting applications as I type this.
In short, I would've preferred an honest answer than the nonsensical "reason" I was given instead. It was a strange and negative experience overall and a waste of my time to be honest.
