It is most important task for me to find my weakness and then work on improvement. I did have two onsite in August 2019 from Amazon and Facebook, I failed both of them. I was thinking today, maybe I should check it out new research topic called personality traits related to very good engineer.
Here is the article I like to read first. I like to compare to myself, what I should work on one by one. I can solve another 100 to 200 algorithms, but I need to learn the basics of personality traits, and then I should figure out how to work on improvements.
