You'll probably be able to get a job, but it will be at a second or third tier company that is questionably managed and considers you to be a cost center. So you'll have no political power and everyone breathing down your neck to get things done - while also having you sit in meetings half the time.
You won't be able to work at a FAANG unless you are have such innate talent that you are basically god's gift to programming.
In addition to all the normal barriers for interviewing, like whiteboard coding, passing leetcode tests, etc, you are going to need to jump the ageism hurdles. For example, the fact that the person interviewing you is younger and is thinking "this candidate is too old".
(And for the 40+ programmers that are going to reply and tell me they are working with tons of older workers: you guys have survivorship bias).
