I received an invitation to interview via email. The recruitment officer was very kind and professional. I then had an online video interview with a member of the team and they weren't very cordial. The interviewer didn't seem like they wanted to be there and was dressed in casual clothes because they were working from home. They could've had at least tried to appear more professional. They were also asking questions in a way that was trying to catch me off guard, rather than neutrally elicit an answer from me.
