all leetcode type questions, i did all the tagged questions / most commonly asked questions for company in question, and if i couldn’t do a question after spending 20 minutes on it, i would look at the answer and then try and understand, reimplement it on the spot, and then a few days later. i had a bit of leetcode experience already, so even if the questions weren’t close to what i did for the tagged, i was able to reason about them. just EM now :)
