First thing is a telephone interview which is well structured - you go through the role, there's time for your questions, all done well. Second is an in-person interview at the actual workplace. Now this is where it gets ridiculous - you'll have at least 4 rounds of interviews with 1-2 people who read the most generic interview questions off a piece of paper. I kept having to repeat examples from my experience because all the rounds were all so repetitive - there's only so many "most challenging aspects of your job" you can think of. It heavily concentrates on frictions so think of loads of examples where you've had problems but came out well. None of the interviews centered around the actual role you applied for, every person you speak to basically concentrates on their own job and how you can help THEM. Nice to know, but hardly vital to YOUR interview. I came out of the second interview (four hours, no breaks as everyone was running over) ready to reject any offer. They make you do a presentation as well, which combined with all the interviews and an excel test is just overkill. I don't want to imagine how working there is.
