Visa Inc. Software Developer interview questions

I applied online on Oct 13, 2016, for the position of Intern - Software Engineering. Got a call only in Feb 2017. Sometimes it takes that long. The interview process was smooth. The first round was some algorithms and data structures questions for 30 mins. Next was an HackerRank challenge that people usually get. It had two questions. Finally, there was an interview with a senior director of a team where he tested concepts in many topics like Java, REST, databases, architectures, etc. Fair interviews, getting the call, however, is the key.

I got a referral from Visa after which I was contacted for a phone call. This was in December 2016. The position was supposed to be in Austin. After the phone call, I had a Hackerrank challenge which had 2 coding questions (simple looping questions), 1 database question and 1 multiple choice question. After the coding challenge, I had a technical video interview with 5 people that was for about 3 hours.
