Microsoft Software Development Engineer SDE interview questions

I applied through campus career fair and got an on campus interview. It takes 30 minutes and asks more on my resume such as the projects I did. There is one technical question to delete all the duplicates in an array. They helped me through the whole process

Got 4 round interviews including an additional one, the whole process lasted 4 hours. All the questions were technical. All travel cost were covered and they booked flight and hotel for me. They have a professional team to process flight booking and reimbursement for candidates. It was the most fantastic interview i have participated. Overall the questions were not that hard, they wanted to see the potential of candidates rather than the answer.
