Got another (3d) rejection in 3 years in a row , this time tried L5 level."Mixed Feedback. Try in a 6 month." outcome Solved all the questions algorithmically, but was rushing and got lost a bit in details of implementation and was fixing along the way. I already worked at Amazon almost 3 years, got offers from Microsoft couple of times, but getting into Google became an unhealthy goal for me since last year. As an Engineer I find this leetcode interviews frustrating and meaningless when it comes to coding. I love algo problems, but when I need to code that out in a 20 min, my thoughts become chewy and lazy. Have to change my mindset to be excited by all this process, but I really can't fight some feeling of "good engineer" vision inside in favor of coding speed etc. Not feeling too depressed, just a bitter taste that I "could" ace it if turn off my mind for a while to convince myself that "this is a great company and interview process knitted by smart people". Pity that, having 8 years experience, I still need to switch towards interview time coding and I constantly fail in that getting "mixed" feedback. Anyway, will try next time again. Anyone in the same boat?
