I applied online. The process took 2 weeks. I interviewed at Visa Inc. (Singapore) in May 2021
Interview
1st round is an online technical test proctored on Hackerrank. 1 hr for 2 questions. So basically if you're unfortunate enough to draw at least 1 problem you can't solve, your chances are slim. I only managed to solve 1, couldn't really grasp the other problem.
Interview questions [1]
Question 1
Easy/medium level data structures & algo. One was related to sorting arrays, the other was something in the lines of counting number of valid substrings.
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.
