I applied online. The process took 4 weeks. I interviewed at SIX (Luxembourg) in Aug 2016
Interview
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)
Interview questions [1]
Question 1
They asked the obvious questions why you want to work for Six group, what is the reason for leaving your current employer. Funny enough the salary questions (which later became the most problematic thing when hiring) came only in the third interview, and was even misunderstood (brutto Vs Netto).
I asked questions about the work atmosphere, and I believe that they told the truth that it's a pleasant working environment.
