Overall, all interviewers were friendly.
Before a technical interview, they gave a test task on Friday to make it by the weekend. I spend my time making it work with authentication roles and unit tests. In a few days, in the interview, the interviewer didn't even try to run the task or even didn't read a code. For one little piece of code (a change from the deposit with coins) I used ChatGpt and talked about it in the interview (it was my mistake). I thought that smart guys understood that it's not necessary to spend my weekend reinventing the wheel with a greedy algorithm. ChatGpt can do that in 3 seconds and everyone should understand this. And this becomes a reason for declining an offer.
Btw, the task is generalized and adoptable for any programming language, I don't like such silver-bullet tasks.
