First round was on code pairing. They have given one design problem and given enough time to comes up with feasible design.
After that two more tech rounds will be there and then 2 cultural rounds.
Tech 1 discussion will cover, dive deep in OOPs, Problem solving using OOPs, Data Modeling, check for attitude to learn, scale, how receptive you are to feedback.
Tech 2 would cover your entire projects, the idea is not just to know the breadth of your projects but depth, how a certain technology was used and more importantly WHY. Learnability, Scalability etc etc where do you go to learn, are you self a learner.
After first technical interview I didn't get chance to give second one....:)
