I arrived at their office and spent about 2 hours onsite. I met with 2 people - the hiring director and his VP. Both were friendly and both interviews were not difficult. In the first interview, there were no really tough questions, however, I did flub a technology-specific question regarding an application feature relevant to my job, due to a misunderstanding of a term on my part, and then IMO had trouble recovering from it. The second interview was less technical, more informational and behavioral. I thought this interview went better. I was then offered a tour of their main facility, which is converted trading floor - unlike any office environment I'd seen before, with about a hundred-plus engineers types milling about. Not sure this is my type of work environment. My biggest disappointment is that despite my taking a half day off my existing job to meet with these folks, they did not have the courtesy to ever get back to me - which is a cold way to say you didn't get the job. That alone gives me some serious doubts about how people are treated in this organization.
