I've been trying to get a job offer for a company in SV for the past 5 months and no luck so far. Do you have any tips for getting a job in SV when you don't already live there (but are willing to relocate)? I've done a dozen or so interviews, and even been flown out a few times, but have never been offered a position. For reference, I have 5 years experience doing python, and I even run my own "startup" as a solopreneur (quotation marks because I'm not doing this project for the money and cost == profit)
