I've always wondered about that lol. Surely there are people who do this? If you dedicate your life to becoming very good at interviewing and bullshitting, you can almost certainly get high paying jobs that you are entirely unqualified for and cannot perform even the basic duties of. Despite this, you should be able to anyways since getting fired from a large company for "gross incompetence" is a long process, especially when you're a new hire and they're liable to assume you're just adjusting to new tools. Pocket those 3-6 months of pay, keep interviewing, and just keep hopping jobs and finding new places to scam without ever actually doing anything useful at all.
