I applied through college or university. The process took 1 day. I interviewed at NTT DATA (Mumbai)
Interview
They'd keep you waiting for a really long time with only coffee to live on. But the interview can go smooth or rough depending on where you want to work. If you give them an option to relocate you, they do not care of how much ever you know. Keep in mind, there are no stripends or perks to an internship with this company in India. So if you really want to work, just agree to relocate and you'll be sorted.
