There was one coding round early on, based on which, four rounds back-to-back were conducted. The interview was fairly easy, but they still pushed you to think about why you were coding the way you were. In all the coding rounds, I encountered the same question: "Describe all possible test cases for this code." This required thinking deeply about the code itself. I imagine this was to ascertain if the interviewee knew and understood what they had coded.

Different, easy enough coding questions, but once you finish answering, what do they entail?

Like, what sort of test cases are you looking at for whatever you coded?

There are two rounds of coding like this, one behavioral round, and one system design round.
