Last week, I finished 2-3 hours of on-site interviews which required a flight and an overnight stay after an initial phone screen, a phone technical interview, and a short technical challenge online.

I was surprised how a couple really basic concepts evaporated from my head during the in-person white boarding. The questions though were reasonable and the interviewers were friendly. All in all a positive experience just an incredible investment of time it seems for all concerned.

The take away is I need to practice solving problems on a white board with just 3 hours of sleep. The sleep deprivation part might be the most important factor to simulate.

Hm. Maybe bourbon? Or a good cider?
