I applied online and had one phone screen and then an on-site interview.

The phone interview covered a really wide range of topics, with a very easy coding question and a very difficult one. I didn't figure out the hard question, but they still invited me for the on-site interview.

The on-site interview consisted of four technical interviews and an additional interview with the manager.

The technical interviews weren't that hard, especially the coding questions, which were really easy. They covered exactly the four topics they sent me beforehand, so it was easy to prepare.

However, I didn't get the offer, probably because I struggled with the object-oriented design questions and wasn't good at SQL.

Nothing really unexpected. One interviewee asked me something about different shells in Linux, which I completely didn't know.
