##Some Categories of IV questions are evergreen

Background - older developers often lament that generations of tech churn threaten our marketability/survival and devalues our expertise on an old generation of technology.

Key is the job interview. Think about the categories of tech questions. Some categories are immune to the churn... If you invest months (years? impractical) preparing for these questions, your investments may, counter-intuitively, endure. Here are some categories --

#1a) Algo + data structure? Yes. The primary focus of Top tech firm like FB, google, MS, Amazon. However, in coding tests they also need working code, therefore you need substantial coding experience with
** STL (or collections) +
** strings -- non-trivial
** pointers

#1b) the algo part -- dense recursion/loops (eg quicksort). Think fast and make it work. Hardcore coding ability. I think you don't even need STL for this.

#2) Threading (only c/c#/java)? Not really un-changing. They do ask java thread pools new features.
** threading algorithms using standard constructs? Yes. often among the toughest IV questions.

SQL? Yes

OO principles as implemented in a specific language? Yes

Socket? not sure

Design patterns? No. a fad.
