1) Questions from project. My project was on REST, so he asked various typical questions on REST(Why, How etc). He later asked me to design a REST API for a part of my project.
2) He asked me to design Uber Cab service. He gave me an instant that there are 5 lakh drivers and they all are sending a request to the server & database at a particular time. He asked how can you manage these requests efficiently. I gave answers by using the concepts of Load Balancer, Sharding, Master Slave etc. and he was pretty much happy to listen the concepts.
4) Later he gave me an instant of above designed uber where sorting was the answer. So i gave him an answer using Comparator of java and wrote code for the same.
