The process took about two months. Initially the recruiter simply ignored me (she claimed that she had forgotten...) so I had to follow up with her. Once they finally moved on with the process, they didn't ask me any Scala related questions even though the position was especially for the Scala role. Instead, they asked be about when to use DFS or when to use BFS, so a typical LeetCode type of stuff. The worst thing however was that they didn't provide any feedback, I've just got a standard copy-paste rejection template message.
