Fujitsu Senior Full Stack Developer interview questions

Teams Video Call. Interviewer did not share his camera online but asked me to share. Why this one way discrimination I don't know. What are they afraid of? It is a technical interview and interviewer asked me a lot of technical stuff. Interviewer seemed a bit full of himself as if he thought taking an interview was demeaning to him. Wanted to catch out the candidate on mistakes rather than seeing whether they are a good fit for the company or not. I wouldn't want to work under the interviewer. Now I'm doiubting about the company too.
