I had an interview where the hiring manager questioned my portfolio

First of all, today's job hunting is BRUTAL.

Secondly, I was at an interview today where I talked about my experience through one of my recent works. After I finished my sentence, the hiring manager asked, "But honestly, how much of this is your work?" I was shocked. I had to show them my Figma file and go through every screen.

But it was not enough: They want me to do a take-home assignment and then go to their office to do another task as well.

After the interview, I sent an e-mail to the HR manager that I'd like to withdraw my application. The HR interview was very good, he was very nice, so if he asks for a reason, I'll explain it to him that trust is very important to me and I feel it's a one-way street.
