A total of four approximately one-hour interviews were conducted on the same day. Three interviews focused on Data Structures and Algorithms, while one focused on System Design. All four interviews start with an introduction, followed by behavioural questions and end with the technical question. The technical part last around 20 - 30 mins. The DS and Algo questions ranged from easy to medium, depending on your level of preparation. All four technical questions may be tailored to the team, especially the system design question.
