Last summer we where actively recruiting (senior) front end engineers in London. To try to filter, part of the first interview consisted of very simple CS related questions:

- JavaScript has a `.sort()`, if it didn't how (or what) would you implement it?

- Can you explain briefly what a Linked List is?

- Given that JS is all about Maps, can you describe me how an hashtable works?

Sometimes just by asking the `.sort()` I got replies like "Why do I need to know that? the sort already exists! Sorry I am confused, I thought I was applying to a senior front end position".

Regarding dev ops (even if just generating the build pipeline) I got answers like "No way! that is hardcore"

Everything else also lacked overall, specially testing.

I can relate from interviewing several people for senior positions. Many had never heard of a linked list and didn't know how hash tables worked.
