If I offered internships I think I'd be lucky to get a few applicants, but I thought internships at top tech companies like Mozilla were very competitive.
And why are you assuming that I wasn't qualified or a competitive candidate? I said I applied on a whim and wasn't drawn to Mozilla for any particular reason, not that I didn't deserve the job?
I'm only reading what you wrote: "I had taken one Android class, knew some Java". I guess I would have expected them to want some related open source work, or a lot of related coursework, things like that.
