YoE: 5 years

One recruiter reached out last year December and initiated the interview process. I schedule first phone interview on Febrary and scheduled onsite interview two weeks after the phone interview. Unfortunately, due to the pandeminc thing. My onsite is converted into to virtual onsite.

Phone: Similar to leetcode 295. solved by using two priority queue
Onsite 1: Decompress a lz compressed string. For example, the string contains a special symbol and follow by a number. Every time encounter the symbol, you need to go back a number of characters and expand it.
Onsite 2: Remove a sub tree that is represented by a array. For example [0,0,1,1,1], root is 0 and 1 is connected to 0 and everything else is connected to 1. if 1 is removed, you should return [0]
Onsite 3: LP question. Don't take it for granted. Prepare your stories
Onsite 4: Domain knowledge. (HW)
Onsite 5: System design

Overall, the experiment is very good but the process is slow. I think people know that Google interview is slow. HR presented the offer to me and told me I had approval from the HC but still waiting for the written offer. Hopefully, everything is fine. My advise to whoever is interviewing is that if you want to get into facebook, try to solve as many medium problems as possible. On the other hand, if you want to get into Google, try to solve as many hard problems as possible.
