Leetcode doesn’t tell you anything apart from someone memorised set of questions and their solution.

For your question, I assume you want people who can solve problems, can explain their thought process and reasons of decisions. I did interview devs recently, and my questions were related to their experience in their CV. Something like, tell me about project X in Y company, what did you do, what did you use, why, what did you learn from it.

My personal opinion is that LLMs are no difference from developers who over engineer and over complicate things. You can get them to do good work with the right steering and right understanding of the whole system within the context of the company.

Conventional technical interview (DSA, whiteboard architecture).

Then 1-2 day paid work trial.

Interestingly…no one has said no to the trial.

It turns out that people want to derisk their decision just as much, if not more.

Recently, I was screen-interviewed for coding speed with a fairly easy project. The company used a 3rd party platform which gave me 90m to complete 4 levels, each one building upon the other.

I think that was a nice test, but the platform is too buggy to recommend.
