Setting the date for the interviews went very smooth and flexible. I had some constraints, and we found without a problem a compromise that worked for all of us. There were in total 4 interviews of +/- 1h30, what seemed rather a lot. In one of these there was a technical test to be performed. So, Six does invest a lot of effort in hiring the best people. After the 4th interview, they wanted to organize another meeting with some manager from Switzerland, but that was (luckily cancelled)
