There was an initial technical interview about Design Patterns.
Then followed five other interviews. Only one of the five was non-technical, focusing on what I would be working on and how the team is organized. The rest were about solving a math problem, an informatics problem, System Design in the Cloud, and Merge Sort.
Each interview lasted for one hour.
All of them asked me what my greatest professional achievement has been so far.
