Thanks. Is being well-versed in C a prerequisite for the role then? I'm imagining you need to be fluent in at least one statically compiled language or ???
In my interviews you code in whichever language you prefer. Some interviewers will ask you to use a specific language that's mentioned on your resume. In general I think that if you show strong coding skills in some language, it is believed that you won't have much trouble teaching yourself the languages your team uses (typically some subset of C++, Java, Python, Go, Borgmon).
