First Round was a general HR round with basic background questions. Once cleared, Second round was an online math test with 30 questions (Medium difficulty). Third was a technical phone interview and I did not get beyond this round. The interviewer did not care to see my attitude and the approach that I take towards this role. It did not seem that his intention was to test me on what I know, rather it was to test what i did not know. He asked me a few warehouse/inventory related questions and for every answer which I provided, he would negate that answer and drill down deeper. If you're an interviewer reading this please understand that we are not a 'Textbook'. There's a level and an extent to our theoretical knowledge and only as and when we gain experience can we progress forward in better handling situations.
