Microsoft Software Engineer (internship) interview questions

It was an on campus opportunity, So we were provided Job ID from Microsoft and were askes to apply on career portal of MS for CGPA > 7.5 and then date for our OA was decided: It was a test of total 80 minutes with 2 problem. Both the questions were of grid type and difficulty lying between medium to hard. I was able to solve only 1 problem so my name didn,t came in list of 40 students shortlisted for interview round. This was my first opportunity.
