I applied online. The process took 4 weeks. I interviewed at Visa Inc. in Oct 2018
Interview
So I applied online and then the next day was sent a hackerrank. I don't remember what the questions were but I got one fully right and then got another mostly right (missed the last few testcases due to time out). A few days later I was sent a hirevue to complete and then they responded a few days after that to schedule a phone interview. After my phone interview I was told to schedule a technical skype interview and then the day after that I got my offer. The whole process took about a month.
Interview questions [1]
Question 1
Difference between relational/non-relational databases, interface implementation in Java and C++, how hashmaps are made behind the scenes, a little bit on stacks and queues
2 medium (string, arrays) and 1 dictionary (hard problem). all leetcode level questions. Interview was in hacker rank with camera on.
The Challenge: Design a data structure to store the strings' count with the ability to return the strings with minimum and maximum counts. Implement a class that increments a string's count, decrements a string's count, gets the key with the maximum count, and gets the key with the minimum count—all in \(O(1)\) time complexity.
mostly ask behaviour questions, like why this company, why this internship, my future career, whether the internship match my career, whether i have right to work there, and they provide the detailed information about this internship
