Replied to an ad posted in the Elsnet list. First, I had a phone interview with an HR person. Then I had a second interview with the team leader and the lab manager. No difficult questions, they were just interested in my background and usual style of work. After this phone interview, I was invited to an on-site interview. Again, there were no tricky questions, I just gave a presentation about my past work in front of several people in the team. Then I had some questions about my past work and future plans, motivation to get the job. At the end, I neither get an offer nor a rejection letter which I did not find very serious.
