I applied through college or university. The process took 2 weeks. I interviewed at Visa Inc. in Nov 2015
Interview
Phone screen - typical HR stuff.
Another phone screen - with the team lead to assess suitability for working with his team.
Three technical on-site interviews with software engineers and then a final interview with the hiring manager.
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.
