I just went to an interview in the morning and got a call from HR in the afternoon asking what you think, just to find out what the hell this is.

This explanation is very interesting to you. They also need to communicate with each other internally. They need to consider some conditions you mentioned. The purpose of calling you is to confirm them. Another possibility is that the boss of the interview post was not there at that time. After you came back, the personnel told him about your situation, and then the personnel communicated with you with questions to see if you met the requirements of the post leader. If I am interested in you, I will inform you of the second interview later. I hope it will be adopted!
