The IBM online assessment consisted of several coding challenges and situational judgment questions. The coding section required solving algorithmic problems within a set time limit. For example, I encountered a problem where I had to calculate the total number of user sessions based on given timestamps and a session timeout threshold. The instructions were clear, and the interface allowed writing and testing code directly. The difficulty level was reasonable, but time management was essential. Overall, the process tested both problem-solving skills and logical reasoning ability.
