I got a LinkedIn message from a recruiter. The first round was a basic recruiter screening, followed by a 30-minute telephone interview. It covered basic Java interview questions, then an onsite interview.

The onsite interview was with five interviewers, each for 45 minutes.

Questions covered core Java, algorithms, and system design.

Four of the interviewers were very professional. The other one didn't know how to interview a candidate. He asked questions regarding frameworks, and you had to know the specific framework name he had in mind. He tried to intimidate candidates if they didn't get what particular framework to use for, for example, a restful call.

They emphasize TDD. I learned that their current code coverage is 30%, which is of course just a number, but that tells you something about their code.

Linked list, microservices, basic core Java.
