Wasted four hours on my valuable spare time to finish a bloody Java programming challenge for the second part of a job interview. The challenge had little to do with programming itself, but more with how to use certain complex frameworks. Although I managed to do the challenge in time, I should have told him to stick it in a place where the sun doesn't shine. I expected a single exercise, the challenge however had twelve. Is that kind of behaviour acceptable nowadays? Maybe I should send them a big bill.
