3 interview rounds. In the first round, the interviewer asked the difference between REST and SOAP. I gave the theoretical answer. The interviewer wanted to know more about SOAP. I told him I hadn't used it, he seemed persistent and kept asking on the same lines. He asked about a design problem for the fast tag. For the authentication with fast tag devices, I suggested the use of public-key cryptography to identify the fast tag devices uniquely. The interviewer could not follow the method suggested.
In the second round, the interviewer asked about problems around heaps. For heapify, I told him the complexity will be O(log n). He said it is O(n) and I was wrong.
Not for people from startup companies like Sharechat, Swiggy, Phonepe, etc.
