I went in, sat down and answered questions while they filled in forms. There were two people and it was during the day, I was going after someone else. It wasn't hectic and they encouraged me to relax and were very friendly and nice.

They walk you in, you sit down with the lab manager and your future trainer and just ask you a few basic questions. They fill in a sheet while you answer however do make you aware that they are listening. You get a call back, not long after.
