I applied in-person. The process took 1 day. I interviewed at Veeam Software (Prague) in Aug 2018
Interview
In the beginning we were given a test for logic and basic knowledge of mathematics. There were also several questions on computer networks, since the company specializes in this area. After that, there was a personal interview with the developer. He also asked a few questions about logic and networks. He further asked how I would test conventional floor scales, and asked leading questions. This was the longest and most difficult part of the interview, about 30 minutes.
