I applied online with a CV and cover letter and was emailed the next day with an offer for an interview the following week. The interview lasted roughly 30 minutes and was held via Skype. Overall I felt that the interview was verging on difficult - some of the questions really pushed me and the interviewer left no stone unturned. If I was the slightest bit vague she would hone in on the specifics of my answer. She also went through my CV in a lot of detail. Following the interview I was told that I would be notified in two weeks time about the result.
