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.
