Over the course of a month, there was a one-hour initial phone interview, online testing, and two separate in-person interviews.
HR "ghosts" candidates after making them go through tests and in-person interviews.
On the day of the final interview, I arrived 15-20 minutes early, but was not allowed upstairs past security, even though at least three calls were made by the security desk. No one upstairs was reachable, so I was not able to at least sit in the company lobby before the interview; I had to wait on the plaza level. Not very welcoming. The interviewing Manager had called HR in another state to see if the interview was "still on;" by the time they finally got someone on the phone, and I was allowed through security, it was a few minutes after the interview start time. This, and subsequently never hearing back from them, was not a positive experience in its final stages.
