I was dizzy thinking, "Do I really have to prepare this much for an interview because you said it was difficult?" but I was able to learn that I really have to prepare thoroughly in case the interviewer asks such detailed questions! There isn't much information about getting a job as a designer on the Internet, and there isn't even much information about interviews in particular... In the midst of that, I think I was able to gain great insight because you explained in detail what questions you could ask based on an actual portfolio and why the interviewers ask them. I recommend it~!
