Interview was F2F online. It was a long process. Started with a problem solving question (simple DP based), and then moves to development questions, OOPS concepts, access modifiers, design patterns, multi threading concepts etc. In some cases, clean code was also required. After this, there was a task given to implement a real world problem in approx. 2 hours time, complete code has to be pushed on GitHub too for scrutiny purpose. It was a good learning experience implementing the sol. for the real world problem in a given timeline.
