Microsoft Software Engineer (internship) interview questions

Interview was several stages, first it was an hour long online text of some mcqs and 2 peoblems to solve, then i passed a certain score so was proceeded to do 2 interviews with 2 junior software engineers. First interview was good, second one I was actually fasting and tired since it was ramadan so I did really badly, what surprised me was that the interviewer mocked me and told me you seem to know nothing about this topic (was hash tables)

Round 1 : Online Test Test was conducted on Mettl. Test consist 3 Questions. All three questions were easy level.Those who solved at-least 2 or 1 and half questions were called for interview. Round 2 : Pen Paper Coding Round Microsoft conducted its interview process at around 8 centers across the country. I was called at Bhubaneshwar (ITER College). Around 50 Candidates from nearby region appeared for process. We were given 1 question (Removing duplicates from singly linked list) and 30 mIn to solve it. We supposed to write the code(in any language) . Judging criteria was how clean your code is, commenting, test cases etc. 20 students were shortlisted for interview round including me 🙂 Round 3 : Personal Interview Interview started with some questions from my resume, about my projects, some real life applications of ML algorithms i have used. Then he asked me a simple question related to arrays(that i dont remember). After that he asked about basic OOPS related questions. Then he asked me to design microsoft search engine Bing. I was supposed to give appropriate classes and functions required to implement a Search Engine followed by some test cases. At last he gave me a situation that if i was given some work which i am unable to complete and deadline is approaching, what will i do .Also the only person who can help me is out of reach. I was eliminated after this round.
