No offense but this comment reeks of bias. For one thing, if by your own analysis, these companies' interviewing processes aren't effective, there's logically a conclusion that yours also aren't, given that interview processes are fairly similar among big tech companies. I've even also heard of an interviewer trying to tell a director with a straight face that a high level IC candidate (L6/L7 IIRC) from a prestigious big tech couldn't solve a "simple" problem at one of those companies. Leetcode style questions aren't even necessarily good proxies for whether an engineer is actually effective at their job or not (and yes, a good number of FAANGers openly admit here and elsewhere that they needed to grind leetcode to pass interviews at these companies). Another thing is that Uber and Amazon are fairly competitive w/ other more prestigious FAANGs in terms of compensation. A decent staff eng at Uber isn't going to be very interested in grinding leetcode for a equivalent role at Google, the compensation delta is just not appealing[0] [0] https://www.levels.fyi/?compare=Uber,Google&track=Software%20Engineer https://www.levels.fyi/?compare=Uber,Google&track=Software%2...
