Interview was about 45 min long, HR and hiring manager was present. Both of them were pleasant and looked genuinely interested as to what you were saying :) I was interested in a research related area, and this was something i felt i would enjoy! I was a bit nervous but the interviewers were really nice so i relaxed after a while. They took turns to ask questions. The HR asked more general questions e.g. strengths & weaknesses and describing events while the hiring manager was more keen on asking technical questions (only a few, don't worry!). Overall I felt it was good. Though in the end the recruiter got back to me saying that I came in 2nd and they decided to offer the job to someone else instead.
