Here what's worked well for me: Always try to be a good coworker. Be helpful, friendly and competent. If you do this well, you'll leave be 5-10 coworkers who are happy to recommend you at each job. They will also tell you the truth about culture where they work. That's pretty much how I have done it. BTW, one trick to learn the real culture is to ask engineers - not managers - during one on one interviews. Few engineers will lie to a potential future coworker in private.
