Not getting a CS/engineering degree is my biggest regret. I would go back and get an engineering degree. I have 20 years of experience and I am a CTO. But even today CTO level openings need a CS/engineering degree from a brand name school. My resume won't make it past automated filters at top companies. When people say education and degrees don't matter, it just fills me with rage and regret.
I suspect that any organisation that filters you out because of the lack of a CS/engineering degree is probably an organisation that doesn't deserve you!
