I had a phone interview with the Head of HR, and had a pleasant conversation. She invited me to come on-site to meet with the team, and do an all day interview with some of the people I'd be working with. After the interview wrapped up, I asked her when I would hear back. She asked me a lot of questions about my salary requirements and acted very interested in bringing me back for a final round the following week. When I sent her an email a couple days later thanking her for the interview and consideration and asking for next steps, I never heard back. I am particularly miffed because I got a ticket when I left the interview which ended up costing me over $500 dollars. I just wish there would've been some level of respect for my time and effort.

I did not apply, they contacted me through LinkedIn. Had a brief phone conversation. Asked me to come in for in-person at 12 noon. The interviewer was so busy we had to walk down the street and grab lunch while interviewing, the interviewer bought lunch, but it was still very casual; felt a bit juvenile and unprofessional. Trying too hard to cater to the "hipster" candidates. They are hiring 90% developers which are typically under 30. But some people still like to be grown ups.
