just my 2 cents, I also have had 5 jobs around the same amount of time, non-FAANG but a diff industry. For me personally, 3 of those jobs were 2-3 years, and the other 2 were short stints at place that were a bad fit. I still get interviews and callbacks and general interest. I only know of one place that was not interested due to the short tenure at some places. It probably also helps that I moved cities to explain some of these hops. Basically I don't think this is such a hard and fast rule that short tenure == no callbacks.
