This was campus internship hiring for 3rd year undergrads. There was a technical test involving 2 coding questions, one of which was fairly simple, and another was also fairly simple, if one had previous experience with coding questions. (I practiced on interviewbit.com, which was helpful to me. Its not a platform to compete like codeforces, but a collection of questions based on topics)

I applied through their website with a referral, after a month or so they sent me a home exam, I think about a month after that i had 3 interviews in the same day, each one around 1:15 hours.
