I was recruited by an employee and Mike Crabtree (CTO) from a presentation. After the initial introduction, I emailed Mike and we set up a time for me to come into the office.
In the office, I met various people on different teams. Talked with some people of similar backgrounds and asked about their experience.
Thereafter, Mike and I went into a conference room where we discussed the in's and out's of the business. We did a technical whiteboarding session.
It was described to me that if I was interested in a formal interview, to please contact him via email and he will set up a time for me to come in and meet with the team directly and go over my resume. Over the course of the next month, I emailed Mike 4 times with no response. Not even a "I'm sorry, we've decided to move forward with another candidate."
Unprofessional and childish.
