Morgan Stanley SDE-intern interview questions

so it was an off-campus drive. I got a mail from their HR with requisite details and then there was Round 1 which was eliminating round and consisted of only two coding questions 1 dp and graph. the difficulty was somewhat between moderate and hard. Somehow I cracked round 1 and then there was a technical interview I could not clear the cut here basically due to my nerves though i know questions but couldnot explain them properly or may be it was my branch(Non CS/IT/ECE) but be calm
