Mystifly interview questions

Had an 1 hour discussion asked one dsa, solid principles and system design pattern like singleton other cs related questions on threads, os level questions. Did had a discussion about 30 mins on the dsa question the approach to solve the question after that had discussion on the listed topics

It was overall good experience but have faced lot of questions with some questions being high level and they where specific of the role or work it was not mentioned that it was a backend role but as fresher they expected to have deep knowledge on backend
