Online Application

I received an InMail from a recruiter at Microsoft through LinkedIn, which had the job description and a link to apply. I directly applied through that link.

Initial Screening

I received mail from the recruiter and was asked about NP, work experience, and invited for a meeting.

General discussion on current work experience and college education, my preferred programming language.

Experience working on C++, multithreading.

The HR told me that the process would involve 3 rounds: 2 technical and 1 managerial, which would be based on DSA and problem-solving.

Technical Round

Duration: 45 minutes. One DSA question, medium LeetCode. Meeting held on Microsoft Teams. Formal introduction. Length of the longest substring without repeating characters. First, I solved it with brute force, then an optimized solution. Challenges: Execute given test cases, and all should pass with the correct output.

Technical Round

Duration: 1 hour. Meeting held on Microsoft Teams. Formal introduction. Asked: 1 DSA question, 1 debugging, 1 problem from the Git topic. Solve: Find repeating and missing numbers in an array. I gave a solution with a hashmap and then an optimized approach with O(1) space complexity. Debug: Find repeating elements from two arrays. Merge conflict question with given parameters by the interviewer: How to solve when the same line of code has already been created by user 1 and merged, and if a second person is still working on problems and has different code on the same line, then how to solve the merge conflict. I solved both questions related to DSA but was unable to explain for Git merge conflict properly.

Find repeating and missing numbers in an array.
