I applyied online on their website. In about 2 weeks I got a telephone call where they asked me whether I have few spare minutes and stated this is not an interview yet, however I believe this could be counted as the first round of interview because after about 5-min chat they offered me a personal interview. That took place 1 week later.
On the first telephone interview I got asked just simple questions like why would I want to work for the company, what I believe this role is about and what could I bring in, also what do I believe their organisation culture is like. It felt pretty relaxed, the interviewer was very nice and friendly.
On the second, personal interview, I talked to two nice ladies, again I felt very comfortable. No real hard questions, apart of the one below, on which I believe you should answer the way how you feel it.
I have been offered the job the same day and I accepted. I am now very looking forward to meet the team.
My personal advise to anyone who want to apply here - just be yourself :) If you are supposed to get the job,you will :)
