BS in CS
5 yoe
Recently went through Google interview process and got asked this question
https://leetcode.com/discuss/interview-question/411228/google-phone-screen-min-time-to-wet-tree
It is a bit cryptic so took me a while and couple hints but I answered and wrote code for dfs.
Probably wasn't good enough as I was rejected. This sucks bad as last time I was atleast able to go to on-site.
Anyways, my recruiter wants me to try again in few months so I'll keep grinding and try again then.
Cheers and be safe
