Visa Inc. Software Developer interview questions

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.
