Interview process:

• Phone call with the recruiter.
• Phone call with the team leader.
• Home assignment with a deadline of a few days.
• Interview at their offices with the team leader and his manager.

I had a big flaw in my assignment, which probably caused me to not pass. I answered the rest of the questions properly, even when requested to code.

During the interview, it was pretty clear I wasn't the candidate they were looking for. However, messaging in front of me while glancing at me felt unprofessional. They could have waited a few minutes for me to leave before doing that.
