I definitely appreciate motivated job applicants (the more effort you show in your application, the more time we are likely to invest with you), but if you walk into a small development shop without an invitation or appointment it’s not likely to go the way you hoped. People are busy doing stuff and there likely isn’t an in-house recruiter or similar to meet with you.

To paraphrase one of my colleagues, it’s like sending someone a note on an online dating site then showing up the next day at their house.

Yeah, awkward.

(It’s happened several times in the past few months.)
