Interviewed over the phone with HR and then the hiring manager and was invited onsite for a third round the following week. The onsite interview was a total mess; first of all I had to chase them down over the phone the day before the interview because nobody had gotten a schedule to me yet ("whoops, sorry!" was their response). On interview day the conference room was double-booked, interviewers weren't on the schedule, and their remote conference system audio wasn't working. After the interview I never heard anything back from them. The most unprofessional interview process of my 20 year career.
Stay away, these folks do not have it together! I think I dodged a bullet by not getting an offer!
