There’s nothing wrong with sending an early email to the person you were interviewed by to simply thank them for taking the time to interview you. I’ve heard good things about doing that. I was told I’d hear back about my job in 3 weeks but was called and given an offer in 4 days. The moral of the story: send a “thank you” email without being pushy, then wait it out. They hate pushy people, but like enthusiastic people. I totally nerded out on my interview, not on purpose, but it turned out well. BTW, did you hear back yet?
