Ask HN: How do you prepare for interviews?

Hi HN, I'm trying to create a tool that helps people with preparing for interviews. I just released the first version, but based on my analytics and some interviews, I've realized that no one really cared for the tool since it didn't solve a big problem people had.

Now, I'd like to understand the problems/challenges people face when preparing for interviews, so if you could answer some questions, that would be greatly appreciated!

- What industry are you in (i.e, SWE, product, etc...) and how do you usually prepare for interviews?

- In your last interview prep cycle, what was the biggest challenge you faced when preparing for interviews?

- What tools do you usually use to prepare for interviews (i.e., leetcode, exponent, algoexport)?

- Name one thing you dislike about those tools, and one thing you like about those tools

Thank you in advance!
