alt Hacker NewsYou're right, but that just shows how fundamentally silly this interview approach is.
In any real engineering situation I can solve 100% of these problems. That's because I can get a cup of coffee, read some papers, look in a textbook, go for a walk somewhere green and think hard about it... and yes, use tooling like a constraint solver. Or an LLM, which knows all these algorithms off by heart!
In an interview, I could solve 0% of these problems, because my brain just doesn't work that way. Or at least, that's my expectation: I've never actually considered working somewhere that does leetcode interviews.

I haven't been asked leetcode questions in a while and when I was asked, it was an easy level problem. I don't know where they ask hard leetcode problems, I also never solved a hard leetcode problem on my own.
Depends on your experience and what you’re interviewing for. At a high enough level, the questions are pulled from the easier side, and the interviewer doesn’t want you to fail.
More exactly, you can't invent algorithms on a spot which took who knows how many years for others to invent. I.e. the question ends up being more if you know about a specific algorithm, which results in "invent it if you don't know about it". It's absolutely silly to test for ability to invent one on the spot, so it's a pretty pointless interview question really.
I was told to use ANY language in an interview. I asked them if they were sure, so I solved it with J. They were not too pleased and asked me if I could use another language, so I did prolog and we moved on to the next question. Then the idiot had the audacity to say I should not use "J and Prolog" but any common known language. I asked if assembly was fine, and they said no. Perhaps python or javascript. I did the rest in python, needless to say I didn't get the job. :-)
