Speaking from personal experience, a bad job can leave your "passion" somewhat lacking. I think if you asked anyone I work with today, they would definitely describe me as passionate. There are indicators that I am doing well there. I can't agree more with this article. I absolutely hate doing tech interviews. I can not code under pressure. Even in the most high pressure situations with an outage or huge customer issue, I always take a step back, think, and try to see what else might be affected before doing anything.

I hate tech interviews so much, that I never do them. I mostly do unconsciously what this article lays out. I would say personally I've experienced better than average hires if I happen to be positive on the person, doing what this article suggests in an interview. I have missed good people (was overridden) and have failed tons of tech interviews where I thought I would be an excellent fit on the other qualifications.

You'll have to ask my co-workers if I'm good, but they tell me I am.
