Infosys Interview Experience for DSE 2023

I participated in the InfyTQ certification exam conducted by Infosys for the 2023 batch. The Certification round consisted of 10 MCQs of Python (I had selected Python, Java is available too), 10 MCQs of DBMS, and 2 hands-on coding problems of Easy-Medium level. I was able to solve all MCQs along with 1 coding problem with 100% test cases and another with 52% test cases passed. I had passed the round and received an invitation for Advantage Round.

The Advantage Round consisted of 3 coding questions out of which I was able to solve 1 problem with 100% test cases passed. I received a Pre-Placement Interview (PPI) from Infosys for the role of Digital Specialist Engineer.
