I've grown accustomed to not getting overtime after over 15 years in the industry, and I make sure that my base salary covers a job where occasional overtime is possible. Should it be different - of course - but if you know that you are for example joining a startup, where the hours can be crazy and the expectations are high, then you should account for that. (Oddly enough, I am working less crazy nights at a startup than I did in the agency world).
