I had to go through two interviews, first with a graduate and second with a partner. The first interview was supplemented by a case study, and was competency based. We mainly spoke about my past internship experience and results from projects I have worked on. The questions were conceptionally not difficult, they just wanted to see how I have dealt with particular situations, problems, etc. The second interview was very similar but emphasised more on what I could give to the company. I also had to do a presentation on which I was asked some tricky questions after. As a whole, quite straightforward application process.
