It was in the office in Cologne with my direct manager and the CTO, in a small meeting room. They were very friendly and understanding, even though I was quite shy. The interview was quick and straightforward, letting me speak freely. I mentioned a problem I had with working on-site, but they explained it was a must. They didn’t seem to know many details about the role itself, and later I learned that the manager who interviewed me has already left the company.
