1. Asked about complete project in detail, current organization, reason of change etc. 2. Write program to implement queue using not more than 2 stacks 3. Write a program for equals() method to compare contents of 2 objects, I used instanceOf operator to verify class type, but he asked me to change it in such way that all subclass objects (with same contents) also return false when compared using equals() method, so I used getClass() method instead of instanceOf for comparison of object type. Interviewer looked to be very impressed after this round, in around 5 mins, got call for next round.
