Hello, I'm Jaya. I would like to share my persistent system interview experience. Persistent System came into our college on 27th August 2021. It came as a pool campus drive .  There were multiple rounds such as the written round(having multiple sections), Technical Interview, and HR round. First-round was a written test on the SHL platform. It has four sections verbal, logical reasoning, technical questions, and coding section or automata coding.  All the questions were easy to moderate. In the Technical section, they focus more on DSA and basic concepts of DBMS and OS. In the coding section (Automata coding) there were two questions:- 1. given two strings we have to find the character which is missing in the second string and return it. It was easy. 2. given a large number and a small number, my task was to check this small number was present or not in the large number. There was a sectional cut-off. There were 128 students who got shortlisted from my college including me. M...
