I have two "short stints" on my resume. Staying in these companies would hurt me a lot more in the long term. It's hard to convince the next employer that you're worth hiring when you're out of touch with modern development practices and your relevant experience is limited to personal projects you did after 8h of wading through mountains of spaghetti code. Last 6 months I have been working on a system which uses SQL stored procedures for everything (including business logic and reinventing parsing of XML and JSON - poorly). Every single time I mention this solution the interviewers raise their eyebrows. Not a single interviewer has expressed any positive feelings about the solution. Am I really expected to stick along working on such an atrocity just so I could put >1 years of a resume?
