Allen Digital Machine Coding Round | Frontend Developer | Bangalore
Summary
I recently interviewed with Allen Digital for a Frontend Developer role, completing two machine coding rounds and a culture-fit interview. I successfully solved two DSA problems, 3 Sum and Merge Intervals, during the first machine coding round despite some in-interview confusion regarding the latter's solution.
Full Experience
I recently had my interview experience with Allen Digital for a Frontend Developer position. The process consisted of three rounds: two machine coding rounds and a final culture-fit/managerial round.
The initial machine coding round focused on Data Structures and Algorithms. I was presented with two specific problems: 3 Sum and Merge Intervals. I implemented the 3 Sum problem using the two-pointers method. Although I hadn't encountered the Merge Intervals problem before, I managed to solve it during the interview.
I faced a slight challenge with the Merge Intervals problem when I tried to trace my solution, especially the 'else' part, on the same document I was coding on, but the interviewer prevented me from doing so. This initially confused me, but the interviewer continued to test my code with various edge cases. Fortunately, my solution proved robust and worked correctly for all test cases. I decided to share this experience since there weren't any existing posts about Allen Digital's interview process.
