I was referred. Ping likes to hire from referrals and was offering $5K per referral at the time. Policy has since changed. First interview was a phone screen. Next was with hiring manager. After that were three technical interviews with coworkers. Following that was another phone interview with hiring manager. Was then called to office to be presented with offer. Process took a few weeks and I never met with anyone in person until I was given an offer letter.

5 x 30-45 minutes chats from HR to sales director. they are all like friendly chats and identity topical discussion. nothing interview like except the HR chat. all the arrangements was easy and mostly I am sure they have not read the CV before hand. completely understand, most ppl are busy. I really enjoy talking to these folks about their ideas and excited about the way they are approaching the issues. I asked more questions than they do in all the interviews.
