I applied through college or university. The process took 1 day. I interviewed at Visa Inc. (Singapore) in Jan 2017
Interview
First, I attend the interview in university career fair. There will be one HR and one Technologist, they are all nice. After a brief introduction of your resume and your strength, they started to give me questions about data structures and algorithm. The questions are not too difficult, but after I gave my solution, they continuously ask in detail and how to optimise. The overall process took around 15 minutes. After the interview, they got my resume and said will arrange me another round shortly.

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.
