Questions posées lors d’un entretien d’embauche pour Senior Java Developer chez CoreFiling

Questions on CV then whiteboard coding of Fibonacci function with discussion of recursion, space considerations, memoisation and its order in On notation. Because I knew Fibonacci is something that I should know, and have come across many times, not knowing it properly stopped me being able to think about the problem: I recognised it as a Shiboleth and froze up. Whiteboard coding is hard: rehearse it as a separate skill.
