If you are reading this review, please note that mine may not be a typical one, as I am new to software development. TripAdvisor sent a senior engineer for the interview, but the questions were basic. The first question related to hash tables: "What data structure do you use to store (or look up) telephone numbers?" The discussion then moved to collision handling (we typically use chaining).

During the real-time coding test, I was asked to handle duplicate spaces among words, ensuring the output had only single spaces between words (or no space between a word and a delimiter). I believe I struggled when using pointers (I used C++), although I still consider it a basic problem. One more point: if you choose C++, it should not differ significantly from C when answering a short question.

Nothing unexpected, just because I'm new to software.
