Is it still a huge deal to have an encyclopedic knowledge of data structures and algorithms? This guy was applying for jobs doing React/Node, which is what I do, and two years after school I cant remember all the details of the sorting algorithms. Would it be so bad to tell the interviewer that if I do anything other than call browser APIs to sort data I am failing at my job and wasting time?
I say as much when people try to pull that stuff on me now. There's a copy of TAOCP on the shelf for a reason, if I need to know a good algorithm, Mr. Knuth's are certainly better than mine.
