Sage interview questions

I was contacted by a Sage recruiter via LinkedIn. The first phase was a test containing 15 questions followed by a coding challenge. The test was about OOP, design patterns, CLI commands. The coding challenge was not very difficult. A typical problem-solving task. The next phase was grilling. It was a chat with a Dev Manager and Principle Developer about in-depth knowledge about async programming, HTTP, RestApi, SOLID, system architecture, etc.

There were different people in different rooms. My group of interviewees would all start in a room. Get asked a question by the person in the room and get about 5 mins each to answer the question and also to ask the person any questions if we had time. We would then rotate to the next room with a different person and different person.
