7,038 senior software developer interview questions shared by candidates

Coding questions were surprisingly easy. One was to write a method that outputs CSS from a weird home-grown version of LESS. IT was all pre-parsed, so all you had to do was figure out how to break out the styles into the correct child elements. Another was to write a method that can look at a collection of (MethodName, Timestamp, IsStart/IsStop ). The goal was to log the time it spends in any particular method, subtracting time spent in child methods. The final was given a set of mines on a grid, each mine having it's own blast radius, return the mine that, when detonated, would cause the most mines to go off. Finally, the architecture problem was to design auto-complete for stack overflows search bar. This is the interview I did poorly in, I think because I went too technical instead of defining the problem better, but I really don't know as the interviewer was not engaged and seemed like he had better things to do. First time in my interviewing that I've had them end it early.

4. Imagine you need to come up in a couple of days, a more or less object estimate of the number of people that speak a given language (for example, chinese) in a given city. How would you do it. You'll have access to public information (like a phone listing?), but not census information. How you do that? What would your approach be?
