Usually a personal and phone interview. Because I was abroad they combined the personal and phone interview. Was a conference call between London and Zurich office + me. Three persons in the line asking questions. Well organised - was clear what will happen and over all a great atmosphere. Afterwards the HR contacted me - had an interview with them too. Then some administrative stuff! Overall the main interview was a great experience but completely different from what one would expect. No technical questions - first stuff about the resume, then all random questions where you can't really give a right or wrong answer. I got the feeling it was more about staying sharpe and not blacking out. Keeping the conversation going, ask follow up question to their questions and be able to shot back if they teas a little. Best interview I ever had and totally relaxed. HR interview was just a regular interview Applied Mid April - Will start Mid May The main interview actually convinced me to take the job. Great introduction of what to expect and the overall experience was just amazing.
