I just got really frustrated with someone who contacted me about an irrelevant job. They asked for my resume, so I sent it to them, asking in return for a job description. A full day goes by, and I don't receive a reply. So I looked up the job on their company website on my own, and it's pretty far off from my actual skill set. So I finally wrote back saying as much, and then told them their lack of response is uninspiring and that I will pass.

That just goes to show my level of tolerance these days.
