I applied through an employee referral. The process took 1 week. I interviewed at Swisscom (Bern) in Feb 2017
Interview
Process started through an employee Referral. I only had to do a presentation followed by some technical questions. The questions were mainly about Machine Learning, but there were also some software engineering questions. It lasted 2 hours. The process was generally fast.
Very nice experience with the interview process. The team manager made sure the expectations I have are in line with the reality. The office space is large and comfortable. There are a number of non-trivial technical challenges to solve during the process.
