Interview Experience

I had applied at Persistent Systems through the AMCAT portal on 12th November 2020. It was a virtual off-campus hiring process. I had to go through an online test followed by two technical rounds and an HR round. Online Test # It was held on 19th November 2020. There were various questions divided into different sections like Computer Science fundamentals, English, Logical Aptitude, and Coding. The quality of the questions was good enough. The coding section consisted of two questions. One was a simple question on arrays. I wrote the solution in a minute and it passed all the test cases. The second question required to implement the KMP algorithm. I had to count the occurrences of a substring in a given string. My solution passed all the test cases.
