I applied through college or university. The process took 2 days. I interviewed at Visa Inc. (Surathakal) in Feb 2015
Interview
It was on-campus. VISA is setting up a new tech office in Bangalore for which they are recruiting from IIT and NIT pretty aggressively. There were 3 interviewers, all pretty big shots at VISA's US and Singapore offices. They treated every candidate with respect and made a very good impression on the students in general.
Interview questions [1]
Question 1
Very varied questions. Equal importance given to a lot of subjects. Check candidate experiences on geeksforgeeks. Don't focus on just DSA.
Had two technical interviews, back to back. Medium leet code problems. Not that hard. After received an email that they did not proceed with me, but had other manager internally interested in my profile
First round OA
Second round interview in which I was given a dp question and then asked about my projects in detailing then we move to some oops and language based questions
The interview process started with a coding test from Hackerrank with 2 easy and 1 intermediate question. I found the questions to be rather difficult given that you are not allowed to use google or check syntax.
