I sent a resume. HR called. That went well, so a more senior HR person called for a phone screen. She was enthusiastic about my answers and impressed that I had worked for a company in exactly the same growth stage and could anticipate their growth strategy. She said, "That's exactly what we're doing!" She told me she'd put my resume in front of the architect and arrange the coding test for the next day. I didn't hear anything for a few days, so I sent a follow-up e-mail to express my continuing interest. Two weeks after that, I got a canned response from the company saying I wasn't a good fit. I may very well not be a good fit, but giving me the impression that I'm doing well and then giving me the cold shoulder is unprofessional. They need to hire experienced and mature HR people.
