I was contacted by their recruiter. The next day, I had a call with her, and within 24 hours, they scheduled a phone interview for the following week. The process was smooth and clear, with no hiccups.

The phone interview was with one of their junior SWEs. He was very nice and polite. We briefly talked about each other's past and current projects and then went straight to the coding. It wasn't as hard as I initially thought; I just lacked practice with that sort of interactive coding. The interviewer was again polite and gave me a few small hints. At the end, he confirmed that I had completed it correctly.

The recruiter contacted me the next morning and asked for another phone call with more senior team members. I am scheduled to do that next week.

The task was for using different data structures in the Java Collections framework.
