I applied through college or university. The process took 2 months. I interviewed at Visa Inc. in Dec 2014
Interview
I was hired as part of on campus recruitments at one of the IITs. VISA was a Day-0 company but their questions were way too simple compared to the rest of the companies in that slot. They have weird hiring policies. Postgraduates with 0 industry experience are directly hired to Senior SW Engg posts. Huge difference in salaries for the same profile based on the candidate's college.
Interview questions were simple. There were some puzzles and some knowledge based questions. The coding questions were too simple and cliche like - reverse a linked list, merge sort, quick sort etc. I don't know how they can identify a candidate's coding skills based on such questions.
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.
