Question were not the difficult ones, but the sub-questions asked on them were tricky.
1st interview question: It was scenario based coding question. Asked to code it in whatever language you want. The question was; you are getting number of orders daily, code a program which will minimize the time right from processing to packing and till warehouse shipment. It was something related to Pythagoras theorem. I coded it with some time left and then was asked to optimize it considering time and space complexity.
2nd Interview: There was not a single question. It was regarding hash tables, sorting and searching, picklists and their time n space complexities. Tried to answer them.
