Got a brief call from the head of department, nothing major. Wanted to ensure that I wasn't an idiot and wanted to make sure I was still interested in the job. 1st interview, I was interviewed by 2 people from the team, and they will test and grill you on your CV. Thoroughly. Be sure to know everything about your CV and examples of why it can be applied to their team. 2nd interview was with the Head of Departments. They are both forcing a mistake from you. This interview is dependent on the role and the job spec. Know the job spec, do your homework on the company.
