As has been said, job applications are a fickle beast. Just because you found success within a few weeks does not mean it's the norm. From personal experience applying to jobs as a soon to be graduate, I know many of my friends with similar qualifications didn't even receive an interview at certain companies, even though I know they would do well in them from work we've done together previously. It's also interesting that I received interviews with all of the top companies I was interested in, but I didn't even hear back from several that I would consider the next tier down. Even better, when I was applying for internships last year, some companies sent me rejection emails in the middle of the summer, seemingly indicating my application was unearthed in the abyss of the job portal by some random happenstance. As I said, fickle.
