Yeah, building a bit of a nestegg helps, but I think I share your concerns on work security. And I think you're right to worry. If you walk out of every failed interview assuming they just weren't a fit for you, you run the risk of arrogance and never properly tuning yourself to the industry and its opportunities. 100% BUT All of an individual's interviews are a terrible sample from which to draw any inferences about the industry and your place in it. Successful interviews give a signal. Failed/Not-followed-up-on interviews give none at all. My point being, tuning and training yourself must be a separate endeavor from interviewing or you will always be in for a bad time.
