I've been doing full stack web programming and server administration for the past 20 years, and I almost never encounter "Big O" notation and algorithm problem solving except in interviews. 99% of the things I have built in the past (and continue to build on a daily basis) consist of just gluing things like APIs together, or building user interfaces that essentially just allow users to display and modify data in various databases. I've had to learn tools like Docker, Git, Travis, Ansible, and Kubernetes. I've had to be able to learn the basics of languages like Javascript and Python and Ruby in a matter of months or even weeks. I've had to pick up frameworks like Angular and React and whatever new shiny thing exists, at the drop of a hat. I have built large web-based software projects that power multi-million dollar companies, and that handle millions of users on a daily basis. I don't have a college degree, and my knowledge of advanced math ends at Algebra. But that didn't stop me from assembling and launching a machine learning platform for the company I work for. But yeah. I don't know shit about algorithms or your "Big O" that you love so dearly and love to judge every "programmer" by.
