Morgan Stanley Software Developer interview questions

first 2 round were telephonic where first was more into technical while second was mix of technical and behavioral questions. They asked me to come to Mumbai from my place by my own and then I had back to back 5 rounds of technical interviews, each of 1-1.25 hrs and they were kind enought to give me a lunch break after 2 rounds. first 4 rounds went all good, I was able to answer most of the questions correctly. Till last round I was almost exhausted and not in condition to speak properly .
