I applied through college or university. The process took 4 weeks. I interviewed at Visa Inc. in Oct 2018
Interview
I met a program director at my university's career fair who then scheduled me for an on campus interview the following day. A few days later I was given a hackerrank - the difficulty for the first question was a leetcode easy/medium and the second question leetcode hard. The following week a recruiter reached out to me to schedule two skype audio interviews- one with a director and another with a software engineer. They asked many behavioral and two technical questions. I got my offer approximately two weeks after the interview after they had finished interviewing candidates.

Question 1
Questions over resume - past internships, projects.

Interview
The interview lasted around 30 minutes. It started with a coding question, and I was given about 5 minutes to solve it. After that, the interviewer asked a logical puzzle, followed by questions on Object-Oriented Programming concepts. I was then asked to implement inheritance in Java. Finally, I was given a binary search problem and was expected to explain the approach from the brute-force solution to the optimal solution while discussing the time complexity of each approach. Overall, the interview focused on coding, problem-solving, Java fundamentals, and algorithm optimization.

Question 1
Coding Question: Given two integers a and b, generate a string containing the characters 'a' exactly a times and 'b' exactly b times such that no character appears more than two times consecutively.

Interview
Reasonable interview. Basic implementation of DSA such as implement a Stack in your preferred IDE. Some theory questions regarding the coding language such as types and defaults. Ex. what are possible visibility keywords in Java and what is the default

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.
