This was followed by Tech interview 1 with 2 Thoughtworkers, where it was more about all data structures, database query, real-time ds, questions based on work experience and data structures used. Then was Tech interview 2, which was breadth and depth with 2 Thoughtworkers it was more discussion rather than question answer type. The discussion was based on the things that need to be focused while developing a online IDE with a rapid increasing user base, we discussed code design, load balancing(clustering), database, request handling. In behind I was questioned on algorithm complexities, college projects, current project I work in and technologies i known.
