I was told that I was going to be interviewed by 2 people, but when I got there, I found a panel of 4, which wasn't very organised at the beginning. They introduced themselves and a brief description of the company and the position I apply for. The interview went for more than an hour because everyone had some questions to ask. They take from my words about my experience and get deep in it, so my advise would be always say what you are 100% keen of. The panel was friendly. There were some technical questions, and some situational questions.
