Sharing the notes that I put together myself for the past 2 years after 10+ interviews, 50+ leetcode contests.
They are not intented to solve a specific problem, but rather some principles that I learned from my failures.
Hope it can be somewhat helpful.

I split it into 3 parts: Coding, System Design, Behavoiral.

Coding

System Design

Behavorial

• There are just less than 10 common questions. Defintitely prepare ahead of time.
• Bring a watch yourself, you need to control the time.
• Don't be a jerk.
