After exchanging a couple of e-mails with a recruiter, I received a screening call. Then, a coding assignment to complete at home was arranged (now they're using Codility instead). After that, I had a technical call with an engineer, which covered some very basic Java and databases concepts. There were questions about how I test my code and how I estimate tasks. Finally, there was a 2-hour onsite interview. The first hour was a friendly conversation with a manager, who asked about my past experience, why I am looking for a new job, and what my expectations are. I could also ask any questions regarding the company and was given satisfactory answers. The next part was a technical interview with two engineers, where I was given a coding problem to solve. They were asking for details and possible complexity improvements of my solution. There were also some general programming and Java questions. At the end of the interview, I had another opportunity to ask some questions. The whole process took around 4 weeks, including the Easter break.
