I agree that it is inpolite to not read a resume or a cover letter. But as a candidate, you can't change the fact that your interviewer is not well prepared. The job will go to the candidate that makes the best of the situation.
The bigger point I'm trying to get at is the following: do not expect the interviewer to discover how brilliant you are on their own. Being smart, hard working, is not enough -- you also need to tell people about it.
The first interviewer told me they haven't read my resume at the beginning of my interview. I tried to highlight my strengths. The other 2 tho told me during the conclusion of the interview, when I asked them what skills they'd want to me focus on if I was to start on their team or any advice for a budding engineer. They both started with something along the lines, I don't know your background; didn't get the chance to read your resume. It was too late to go over my resume as I was being escorted to my next event.
I will be more proactive on my next interviews. I did have my github on my resume; I will add more projects to it and get involved in OSS.
