Yes, but would you forgo a well paying job because the interviewers asked you questions that weren't things you did as a day job?

The employers need metrics, fairly standard ones, to filter out unqualified employees and these sorts of simple algorithms and data structures are the least bad ones.

Where I complain is when the interviewer explains "to solve this problem, you need to think of them as virtual ants that can pass through each other" (yes this was actually what my interviewer said for https://leetcode.com/problems/last-moment-before-all-ants-fa...).

> The employers need metrics,

I'm guessing some do, the kinds of employers who attract a lot of applicants who misrepresent their education and experience.

I have never been asked to write code in a job interview. I guess I've been fortunate to find employers who look at my resume and talk to me as a person not a metric.

You generally have to use them, not implement them. Though a linked list is so simple that I think anyone calling themselves a programmer should be able to do it without any particular preparation.
