CIBC Intern interview questions

Had a hour technical interview with a senior or a director. I don’t know his position but he was really old. First red flag was the random interview invite without checking in with my availability a day before the interview. During the interview he asked me really random questions like how did you install 000, how do you check the version etc that I found really confusing. He went in depth with my resume but idk the format was really confusing. It was really exhausting.
