• Then he ask in which Subjects you are comfortable with like DBMS, CN, OOPS, DS etc.
• He asks SQL VS NoSQL
• What is heap sort? and its time complexity
• Then he asked LinkedList Questions Nth node from the end of the linked list? I say we can traverse the LinkedList and find the length and then we can traverse again and return nth node. He was not satisfied with the solution he told me to do the question in one pass and also not use any extra space. I was not able to give the optimal approach then he ends the interview.
