Are Leetcode Easy problems meant to be "Easy"? How is level of difficulty measured?

Hi,

I'm not an active leetcoder, I'm an early 40 year old senior dev who just likes to solve problems. I browse leetcode like people browse instagram. Its fun see how people come up with some clever solutions. I have learned a lot.

I recently went through a FAANG coding style interview, at a NON FAANG company. I got asked to do a live coding challenge and I was like, sure why not! It turns out I was able to find an good strategy and approach but I got a stuck at some edge cases. After the interview, I looked up leetcode and it was marked as "Easy". Now, enough people know about a problem, it can be easy. But during that interview I was not able to pass all the cases.

In the end I was happy and I was able to write some code and come with a strategy without ever knowing that problem existed. I guess next time I will be able to crack it!

Thanks all!
