I don't know if you work in FAANG or no, but most FAANG interviews just don't work this way. So, as much as I like this style, it's just 1 company and definitely not the norm. The rest of us are stuck with design Uber, Whatsapp, crap...
Sorry. Countless articles have been written about how interviews should be conducted. But nothing changes. There are thousands of engineers vying for FAANG/MAMAA and they’ll do backflips to get a job there; leetcode is nothing for them. Some do it to get better salaries as your compensation drops after the 4 yr cliff, some for prestige. So unless you can influence these companies to change nothing will change.
