I have got so much help from leetcode community so I am sharing this to give back to everyone.

Here is my background

• I did not finish a CS degree but went to a top 10 school that is well known in the US for 2 years .
• Interned at google
• Started a company and ran it for 1 year
• Senior engineer at another comapny (much smaller)

I had 2 coding rounds

First Coding

• implment power function
• Variation of simplify path

Second Coding

• Two questions I had never done before, could not find on leetcode

For my coding i did not get the simplify path problem finished.
I finihsed other coding questions very quickly.

FYI I had bugs in every single question but i got the main ideas correct.

**2 design rounds **

• Top k problem (Deesign top trending, this was a coching interview i think and maybe did not count)
• Design Internationalization (Long discussion with interviewer, did not go down the function/non functional route, we dove into API and implemtation details)

1 behavioral

• Really wanted to show my growth here from being an intern to becoming senior at my company with the way i answered. I wanted to give signal for e5 since I was shooting for e4

My recuiter reached out to me saying she wanted to talk. I thought it was a reject since my interview was not close to perfect.

Learnings:
Review basics of data structures.
Do top 100 fb tagged.
Do no more problems except ones to make you stronger in weaker areas.
Mock interview like crazy, if possible line up a couple interviews before facebook. I did not line up nterviews and I was nervouse like CRAZY!
