Comp Science major here, I still think these type of questions are not relevant years down the road, unless you explicitly are working with them. (eg. most database systems, log storage, and such will have to deal with such optimizations). If you do, then it is fair to ask. But I have seen interviewers asking questions like these even for folks that would not need them . (aka, mobile development, of front end JS) It is like asking a motorcycle racer/driver on whats the fastest way to swap four wheels in a F1 race.... Makes sense of the formula 1 driver, but not for the 500c motorcycle driver. Unfortunately our industry is filled with lots of self-congratulating types that use interviews to inflate their own sense of self worth.
