I applied online. The process took 3 months. I interviewed at Visa Inc. (Singapore) in Feb 2020
Interview
Very straight forward. There were about 3-4 rounds of interview. 2 or 3 coding rounds and 1 behaviour round. The questions are generally medium level difficulty. If you do leetcode medium and some hard just to prepare, you should be good.

Question 1
- given a large paragraph, what is the most optimised way to reverse it - reverse linkedlist
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.
