Responded to a craiglist ad. After filling in a quiz about SQL queries, the CEO griped me about not knowing SQL; I wrote MYSQL queries and not MS SQL queries as maybe he was expecting. I was then asked to solve a riddle involving marbles and weight. Large amount of cubicles, conference room was nice but the employees seemed to be packed like sardines. The office building was nice but seems to have no other tenants. All the workers had a general sense of misery; they didn't seem like they wanted to be there. I was told we can talk further if I agree to commit myself for 2 years; I'm glad I didn't get an offer.
