Round 1(Aptitude Test-1): Persistent Systems conducted a selection exam consisting of aptitude questions, technical MCQs, and 2 programming questions on the Aspiring Minds platform. 

  • One question was to remove vowels from a string. 
  • Another one was related to arrays. 
  • After a few days, they shortlisted around 65 students. I was one of them.

Round 2(Aptitude Test-2): The same pattern of aptitude questions. 2 programming questions:

  • One was related to dynamic programming 
  • Another one was related to string.

Round 3(Personal Interview): The interview was conducted on the Smart meet platform by Aspiring Minds. 

  • Firstly, the interviewer asked me to introduce myself. 
  • Then she asked me to explain OOPs concepts of JAVA. 
  • Then she went on asking questions related to abstraction, polymorphism, inheritance, final keyword, etc. 
  • Then she moved on to DBMS. She asked about normalization, ACID properties, joins, etc. 
  • She also asked about CN. Some of the questions were ISO-OSI layers, TCP/IP layers, hub, and switch difference, physical topologies, etc. 
  • Overall it was an amazing experience to get an idea about my strengths, weaknesses, and areas to work upon.
