I applied online. The process took 1 week. I interviewed at Visa Inc. in Jan 2018
Interview
The first round is a 30 minute technical phone interview. It was fun to go through the questions with the interviewer especially beacause he was hinting me whenever I got stuck. I was asked basic data structure and algorithm questions (example - how would design a random number generation function, what data structure would you use to store the web pages visited by a user as he clicks on the forward and back buttons in the browser). Just try to think as logically as possible!
Second round was a hackerrank challenge - 3 questions. Could solve only 2, was rejected after this.

Question 1
what data structure would you use to store the web pages visited by a user as he clicks on the forward and back buttons in the browser?
I only took the OA definitely failed. One was similar to 3sum, another was a stack question and the last one was DP / Greedy.
I haven’t studied much leetcode so it was difficult for me to do these problems
First, a recruiter screen phone call. Then, a technical interview asking LeetCode-style questions is usually just easy/medium difficulty. Finally, two rounds in one day, one behavioral and one "non-coding" technical, but expect to write code.

Question 1
What's the difference between a process and a thread?
Pre-screen on hackerrank. a little challenging in my opinion especially with the time constraint. make sure to grind leetcode heavy especially easy and medium and that you're able to easily finish it.
