Infosys DSE Interview Experience 2021
I got a PPI interview opportunity for the role of Digital Specialist Engineer after clearing the first round of HackWithInfy 2021. The first round was held on 9th May 2021 and consisted of 3 questions- 1 Easy, 1 Medium, and 1 Hard. I solved one question completely using memoization and passed only the sample test cases of another question in this round. My interview was scheduled for 26th July 2021. I was informed 7 days before about the 40-minute interview.
The Interviewer joined the room and firstly introduced herself. Then, she asked the following questions:
