OK, the administrator could have been a little more precise then. Unfortunately the LeetCode page also does not contain a clear title for the page, which make the administrator's job harder. Changing the title on HN is probably done after a quick one-time impression at the site.
(I don't think that we can see the original title as posted to HN?)
The original one was like "Most engineering interview questions of hot companies". My point was, very few companies are innovative for recruiting. Interview questions can be practiced, which only test a small subset of skills for software engineer position.
Well, I can see the reasons for a title change then; the page does not really explain the claim in the original title. It is an interesting collection of problems applicable for a coding interview -- which is not the same as "most interview questions" -- and it doesn't mention the companies (hot or not) that asked them. Nevertheless, it's a good find and a relevant submission to HN.
Somewhat a different approach here, devdraft.com. Just heard about it.
