Microsoft IT, Hyderabad came on my college campus providing internship to selected students. A quick elimination in written test was followed by 4 rounds of interview ( 3 tech + 1 hr).
Interview for college students is not herculean hard. Stick to basics - data structures, OS, OOP, databases. Be sure that you know A-Z of everything you mentioned on your resume.
I did get selected as an intern for 8 weeks at MS IT, Hyd. The work culture is awesome, with all the perks you can wish for including pool tables, tt, free beverages and such. The people of team that I joined were supportive and the work cut out for me was definitive. So just worry on how to get there, and not on what will you do once you are there.
