It was an hour long remote technical screening interview for C++ via a provided Zoom link. We spoke briefly about my work history and then got into some technical questions where I was asked to analyze some basic lines of code and indicate what it was doing (basically establishing I understood pointers, references, lambdas, and move semantics).
The last half hour was spent on a programming question, in which the solution involved using a depth-first search to efficiently identify particular node clusters in a graph.
