Honestly a more laid back interview than other interviews, what they mainly want to see is your confidence and knowledge on the market you want to work in. Not too much preparation needed for the interview.

I was called on the phone and asked if I had time for an interview. The interviewer was quite nice and respectful but also direct and focused. My interview started with a couple of ordinary questions about my CV, particularly why I applied for a sales position despite having limited sales experience. Then I was asked a couple of questions about key skills required for the job and how well I think I can demonstrate them, particularly cold calling. After mentioning cold calling, I was told to pretend to be making a cold call to a company, after which I had to evaluate my performance.
