I had a call with an engineer on their team. I signed an NDA, so I can't go into the specifics of the interview.

After the call, it was very difficult to get a response from HR. I think they were interviewing other candidates in parallel and had me on some waiting list, so they weren't willing to provide a concrete response.

I wrote to them about once a week. HR would promise to get back to me by the end of the day and then would not contact me. Finally, she told me they found someone else when I contacted her about four weeks after my initial interview. She forgot to update me after they had made a decision.

I think my interview process was handled poorly by them.

I signed an NDA.
