A recruiter initially approached me. After the screening call, I received an online test and then entered the first phase of technical interviews.

I had interviews with two different people.

The first interviewer asked questions but never showed interest in listening to my answers, moving on to other questions. It felt like he was just trying to unsettle me. He also didn't use a headset, so I had to listen to an echo and deal with his bad internet connection.

The second interviewer seemed a bit better, but he asked a question and then said we were running out of time. That was really annoying; he could have simply stopped asking questions if he was running late.
