Do you know of any examples where a person can't/ might not be able to solve at least 3/4 questions in leetcode contest but still got selected in Google or Facebook or equivalent difficult algorithmic interviews?
No, when you fail you don't get it. Even if you pass, you might not get it.
I doubt. Leave FB and google, I doubt they will clear any decent paying tech company.
Yes, you can re-apply. It only takes one successful recruiting cycle to get in.
Yes, I know one girl who only solved 2 problems and got accepted to Google.

2 strong hire still beats 4 lukewarm hires
Probably not. But I used to be the one who solved only one problem during the contest. Now I can solve all within an hour (usually ~200th place) and that's when I start getting offers from FANG. Now I am in one of those. Just keep doing. Eventually you will get there. It is like an weight training. It feels like 300lb deadlift is impossible to do so. But after a long practice, you can do it. Not giving up is the key.
How much time did it take for you to go from 1/4 to 4/4?
I think op means specifically unable to do well in the weekly leetcode contests on saturdays, but managed to pass google/fb interview.
Yes
