Microsoft Software Engineer - Internship interview questions

it was a little bit hard but actually, it was good and I gained some more experience from it but actually, I discovered I had an interview a little bit late because I didn't check my email(my problem) but the experience as a whole was good actually.

Coding test + Algo test on pen and paper + Interview R1 (DSA problems with emphasis on graphs) + Interview R2 (Resume + Project discussion) + Interview R3 (DSA problems + debugging ability test)
