In this round, they completely check your skills how you are applying your knowledge to the problem. They will give you a real time problem and asks you to solve. They conducted 4 exams on that day.
1. Circuit theory and EDC
2. Digital designing
3. Programming
4. General questions.
These 4 tests consist of the complex problems and we need to solve them on paper (they conducted this like an exam). For each test, they give one and a half hour time. After the tests, those papers will be sent to interviewer and you will be called to the room where they interact with you about what you were written.
In circuit theory, the circuits are given and asked to find a node voltage or asked to design a circuit based on the theorems.
