I started learning Big-O a few months back and I have been working as a programmer for several years, not knowing about Big-O didn't stop me from becoming a lead of a development team. Knowing about Big-O is important but humans learn more from experience (aka. trail and error) than anything else. I started learning about Big-O just because I am interviewing right now and many tech companies love to ask those questions, but if I were not interviewing I would probably leave that topic for another time.
