They flew me to Chicago where I spent several hours doing tests. 2 hours in the morning on skills testing then 3 1 hour interviews after lunch: (a) pairing interview: some pair programming; (b) technical interview; (c) values and consulting interview. It has been a while now but what was clear was that they were probing me for my political opinions. That was surprising and seemed unprofessional. I was mostly non-committal in my responses. I had the impression they were looking for more enthusiastic endorsement of the various political causes they mentioned. They apparently don't want a diversity of opinion within their walls. No offer. Quite happy to pass them up too. Struck me as being a rather odd shop, condescending, intolerant, unprofessional.
