Persistent Systems Interview Experience 💻

Persistent Systems offered on-campus jobs at my college. The role was Salesforce developer. The drive started with a pre-placement drive from the Persistent team in which the company culture, salary structure, the distribution of packages based on the performance in the interviews and so on were discussed. Persistent Systems is a large corporation spanning in multiple countries and various states of India. The screening round was held on next day after the pre-placement talk.

It was a pretty simple exam that was conducted on the AMCAT platform and consisted of English, Computer fundamentals, Aptitude questions and 2 coding questions. Both the coding questions were extremely simple based on array operations. Aptitude questions consisted of basic seating arrangements, permutations and combinations, syllogisms and number theory questions. Computer fundamentals were equally easy if you've studied the subjects like Operating systems, DBMS and computer networks. I passed the exam and got selected for the next round.

The next round was conducted for a higher CTC. It was similar to the previous round and was conducted on techgigs platform. The level of questions was slightly increased but it was still pretty easy. I passed this round as well. Students who could not clear this round got their interviews scheduled for the base CTC. Passing students went on for interviews for the higher CTC.

My interview was scheduled 2 days after this exam. It was a live video/coding interview conducted on AMCAT's live IDE platform. The interviewer was a tech lead at the company. The interview started with greeting each other followed by a coding question, SQL problem and a few networking questions. The coding question interviewer asked was "Count the unique words in the given string". The interviewer looked satisfied with my solution which consisted of using Hashmap. Again easy level Leetcode questions. The SQL question was also very simple (1 line SQL query). Networking questions consisted of how does DNS works? How are HTTP requests processed?. The interview ended with the interviewer looking pretty satisfied with the interview.

From here the next option was to go for a higher level round offering an even higher CTC which I didn't go because of my college placement policy of not allowing placed students for other companies unless the company offers 2X times the CTC than the current placed salary.

Next a simple 30 mins automated HR round was conducted. 3 weeks from here I got a Congratulations email from Persistent about being selected for a 6-month internship + full-time offer following it.  The overall interview was simple and required basic coding and computer fundamentals knowledge to crack.
