The HR recruiter first briefs you on the role and answers your questions and explains the process. You get a remote video 1:1 interview to see if there is potential to go to the next round. If you are approved, they fly you out to one of the main recruiting offices (in my case, I had the choice between Zurich and London). You are flown, boarded and asked to keep receipts to be reimbursed for eating and travel expenses. You are asked to prepare a couple of case studies to present to the people who will be interviewing you, some of them in the office, some remote. They set up also a more relaxing, unofficial lunch with someone from the team so you can ask all the questions you want. I feel like the interviewers are briefed not to smile or nod, so you speak to some stone-cold-faced people. They asked about methods used. After I've gone home, the recruiter calls to give feedback to say what went well and didn't. I think they make the experience as smooth as possible. But they definitely take the position that they are interviewing YOU for the job, and not that you're interviewing them as a company, which I find off-putting. Particularly since they asked me to apply.
