This extends to every test though. My ACT score jumped massively on my second try. The reason: I didn't realize how much little time they gave test-takers, so I ran out of time on some portions. The second time around, I rushed through as fast as possible.
In a "can you solve this new leetcode problem that just came out and is not in the training data"? Awful.
If you want to see an example of a new problem check out https://news.ycombinator.com/item?id=37910297. You'd think if leetcode makes you good at solving problems then it should be doable any higher ranking leetcode programmer.
The comment I replied to claimed that "LLMs would do pretty well at leetcode interviews". OpenAIs own report [0] shows how GPT-4 fails miserably at medium/hard leetcode problems that are not in the training data.
Or do you do well solving the problems on your own and just have trouble when being interviewed?
I did extremely well in algo classes in school.....but since then I have built actual applications that run businesses and haven't used algorithms at all.
Grinding leetcode feels like running on a hamster wheel for me.
