I used to work part-time as a frontend developer for software company in college. I was also trying to finish up my CS degree in my fourth year of a not so well known college. I had built some interesting apps at the time (with lots of backend infrastructure, and heavy js), but my boss could not look past pedigree. I was not a programmer as far as he was concerned, which was really disheartening and shattered my confidence. I kept going on interviews and I was eventually able to move to a programmer position, and haven't had much issue since then being taken seriously as a developer (at a few major places). All you can do is keep trying/interviewing, and approach every company with a sincere assumption that they will give you a fair chance.
