It wasn't an interview per se but the system check. It was easy comfortable especially for my first "interview". The system check was used to check everything was working and to get to know you a bit about you and help you with the rest of the process which involved a demo class.

Easy and efficient, I found everyone that was involved was clued up with the process, as long as you study the material, you will be fine. Easy to comprehend, easy to follow, easy to understand
