I applied online. The process took 2 days. I interviewed at Visa Inc. (San Francisco, CA) in Nov 2018
Interview
Talked to a recruiter at a career fair who first asked about the stuff on my resume and then later told me she would contact me with the online coding interview link. Completed 75% of the interview correctly(hackerrank) cause i hadnt learned data structures yet so in the end I think that was what led me to getting rejected.

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.
