Persistent Systems Interview Experience | Off-Campus 2020
  • Last Updated : 03 Jan, 2021

Round 1(Technical Test of 45 minutes Duration): After successfully filling all the details I received an email regarding an online exam which was held on 10 December 2020 on the AMCAT platform. The test was an MCQ based on questions from subjects such as DBMS, Data Structures, Operating Systems (ENTIRE SUBJECT), Computer Networks, and OOPs Concepts.

I have prepared all the subjects only basic knowledge is required. So overall this exam was easy and the ones who prepare the above-mentioned subjects well will be able to make it.  After this, we had a logical reasoning section, comprised of questions that are easily available in RS Agarwal Reasoning book, so practice it well. As far as my performance is concerned I did take time in doing these questions since they were lengthy. The third section in the test was English for which I cannot judge how exactly my test went but I’m pretty sure you will be able to do it.

Round 2(Coding Section Duration 45 minutes): This is a combined section so when you are done with your technical section MCQs you will be directed to the coding part. There were two problems. Both the question was based on arrays and string you can choose the language of your choice. The first problem was based on finding the number of vowels from an input array (space separated). There were in total 15 test cases out of which 2 are visible to you. I was able to pass 115 test cases in total and then I moved on to the next code. The second problem was comparatively time taking and but it’s also very easy and I solved both the question. It was based on sorting as well as arranging the elements of the array. The total number of test cases was 12 and I passed all the test cases.

Round 3(Technical Interview Level 1 Duration 30 minutes): After 7 days, (17 December 2020) I received an email for being shortlisted for the Technical level 1 interview which was to be held on 18th December 2020. So I had exactly 18 hours to study. All the subjects mentioned above in the technical assessment were a part of the interview syllabus. Primarily I studied DBMS and Java for interviews which are mandatory. The interview was held at 1:45 pm on 18th November on the Smart meet platform (virtual) and the following were the questions:

After that sir, told any question for me: I asked what are the improvements that you want in me so that it will be beneficial for me and I can be proved a better asset for the company?

Round 5 (HR Interview 15 minutes Duration): So for this, I was informed on the next day (22th November 2020) that too hardly one hour before the start of the interview. So keep on checking your emails. The interview was scheduled for 15 minutes but it took only 5 minutes only.
