I applied online. The recruiter reached out via email to schedule a phone call with him. I replied with my available time slots, and then he ignored me completely. After a month, I received a rejection email. Very unprofessional. Don't waste your time with them.

The interview process started with a brief easy screening with HR. And next I had two hour meeting with a software developer and team lead. We talked about my previous experience and then started with a medium algorithmic problem. Briefly talked about things like containers and complexity, inheritance, move-semantics, etc. Also there was a debug section. Be ready for geometry/algebra questions as well. Interviewers were very friendly and nice.
