Cisco Developer interview questions

Stage 1: Codility: 3 tasks, 200 minutes, C++ (difficulty from easy to medium) Stage 2: Webex interview with hiring manager and team: past experience questions, behavioral questions, Codility assignment review Technical questions regarding Codility assignment were mostly about algorithms performance and not clearly stated (e.g., is it possible to improve the space complexity of this task?) and after all, they stated that "Familiarity with programming language was not strong as they are expected" given a fact that they didn't ask about language features and techniques. Very disappointed.
