the goal of an interview, apparently, is to see to what extent the applicant was willing to repeatedly grind the same leetcode problems over and over again and memorize their solutions
i was in a FAANG interview where i was asked such a question that was internal and straightforward. the person assumed that the way they were doing this, was common industry practice. however, i have been in that particular specialization they were interviewing me for for a good 20 years and never heard of a company doing it that way. i am quite sure that the person mistakely assumed that because his FAANG did it that way, it must be industry practice.
