Reciting algorithms is reverse gatekeeping. If an employer wants to grill you on them, get out of there.
If I interview someone I don’t go deep into algorithms but I want to know that they know how about binary search or hashmaps. Ignorance of these shows ignorance of the basics of computation.
The tech industry has normalized to the state of asking such question - its rare to be interviewed on domain expertise, unless you are interviewing at a fortune 500 big corp.
I’m sure it’s popular. But it’s not everywhere.
