One phone screen/interview which leads to one in-person interview with 3 different people that 20 minutes each.
In-person interview consists of a mock call which you need to try and schedule a demo on the phone, overcoming typical objections. First person comes in and asks you some questions, second person listens in on the mock calls and gives you feedback and helps you prepare a bit. This is to determine if you're coachable or not. Third person asks you some more questions and then you're done.
