Target Lead Engineer interview questions

First contact over the phone with recruiter was no problem. Second phone technical screen was with a lead engineer that had no clue what to ask. Then he started asking questions about experience and then he asked a couple of technical questions that I answered correctly and he kept changing the scenario to try to get me to answer incorrectly. Weird!!

case study + 2 technical rounds + director round. a NP-hard problem was given in case study . basically a rest wrapper over cab routing algorithm. Interviewer was not able to digest graph based approaches suggested and just cared about CRUD. Followed by 2 technical rounds. Interviewers came with a word stuck in mind approach. If you were able to say that word you will be selected. They overcrowded the interview process. Had first round at 2 pm. Being an IIT alumnus and having worked with companies like microsoft/intuit etc. I wouldn't recommend it.Not a single line of code was being asked to write. Only good thing was free lunch was provided.
