Experience:

This PhonePe interview experience from 2021 resulted in a selection. The process included three rounds: Technical Round 1, Technical Round 2, and an HR Round.

Technical Round 1 was based on DSA and involved three questions. The first was an easy question: "Given an array, check whether it is possible to get two numbers from the array with sum k." The second was a hard problem on graphs, where the candidate discussed their approach. The third question was "Convert string a to string b. You can do the following operations on string a: 1) replace a character, 2) insertion of any element, 3) delete any element. Output: Minimum number of moves to convert string a to string b." The interviewer was impressed with the candidate's problem-solving skills and approach.

Technical Round 2 also focused on DSA, with three questions. The interviewer asked the candidate to implement the third question from the previous round, which was "Given a string s, output all valid IP addresses we can make out of it," solved using backtracking. The interviewer was quite impressed with the candidate's problem-solving skills and how they approach any problem.

The HR round was described as "somewhat scary," emphasizing the need to be prepared and genuine. It started with interviewer and candidate introductions, followed by general questions about the candidate and college. A significant portion involved discussing projects in detail, with many in-depth questions requiring a great understanding of the projects. Core OOPs knowledge was tested with output-based questions.
