I sent several emails to their hiring manager with a portfolio and resumé. Maybe 2 weeks later I received a response and the go-ahead for a phone screening. The phone interview was about 10 minutes long before they decided to bring me in since I was local. So in late October I went in to interview and had several rounds of softball questions. One of the managers was mildly condescending when discussing the resume. Overall, the interviewers were impressed with moderate competency in CS and engineering. The long and short of it was I passed the interview, sent a thank you card, and waited for a response. Over two months later I sent a follow up email and then they suddenly wanted to go through hiring talks, so that I could start three weeks later.
