The questions asked to me were related to OS concepts like deadlocks process and threads n all. From networks they asked me about the wifi drivers installed in your system. They asked about dynamic programming and they gave me one question to solve using dynamic programming. Then they asked me to write two more codes . From database they asked me about the errors which we will get if we do these things in the table. They asked me about the hashmap and how does it work and why it takes constant time in data retrieval. They asked me about the OOPs concepts and the virtual class implementation in detail. In short they asked me questions from every field."
