I have interviews lined up with google and coinbase which both are going to ask leet code style questions. I'm going to go through it just for the promise of more $.

Even if it is annoying to spend hours and not get an offer, I can see why they ask these types of questions to see your problem solving ability first hand.

I would expect any decent engineer to be able to solve leet code style question, or at the very least be able to model the problem reasonably well and give a recurrence. Even if the code contains errors or there's missing edge cases then it allows you to see how someone approaches a problem.

Leet code style questions are basically a bunch of combinatorial algorithms. Even if they seem like a different trick each time there's general techniques that can be used to approach each problem.
