How many hard leetcodes do you need to pass the Google interview?

Once you hit 1337 solved hards, you immediately get a job offer from Google. But only if you have an active gmail account

I did maybe 10 and passed. Tbh I think doing mediums quickly and effectively are much more useful. YMMV though ofc, mostly it is a function of luck and who interviews tou.

Are you trying to get top contributor or something? It seems like you make a post every hour. Spend some of that time actually doing leetcode.
