I applied through university. The process took 1 day. I interviewed at Visa Inc. (Allahabad) in Aug 2018
Interview
Before the interview there was an online coding test which consisted of 4 coding questions.
After that candidates were selected for the interview round.
The interviewer focused mainly around the project. Since my project was related to somewhat E-Commerce app, he asked me to design a user login system. How will I match the password from the database. Both encryption and decryption methods. I told him about the salt method.
Then he asked me about database design that I used for my project.
He also asked questions related to Data Structures.
Interview questions [2]
Question 1
Given a number N, find the number of ways to represent this number as a sum of 2 or more consecutive natural numbers
I don’t remember this question exactly but in this question we have to find the minimum length of the substring present in the circular string from which another given string can be made.This was solved using binary search and window sliding.
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.
