There are many interviewers but boomer ones will make you uncomfortable especially if you are younger or fresh grad. Boomer will look down on you because of your experience. Just be confident, know how to handle boomers and never mind them. HR called me for interview for engineering position while I do not have engineering cert and never put 'engineer' in my CV. Nevertheless, I came to the interview just to be informed that I'm not suitable for that position because I don't have the cert.
