All the students from B.Tech CSE/IT, who had CGPA 7.5 and above and with active backlogs were allowed to apply for this drive. They came to our campus for the role of Technical Analyst.

ROUND 1(Online Test): The first round was on the HackerRank platform. It consisted of  6 coding questions. The time allotted was 2 hours.

And, the coding questions were of medium to difficult level. All 6 coding questions were of 5 data structures (array, string, linked list, tree, trie). The difficulty level of question increased as you go from array to trie. One question was from dynamic programming.


  • If the code passed a few test cases, then it showed as ‘partially executed’.E.g.: if there are 15 test cases and your code could pass 14, then also it will be considered partially executed. So, you must focus on the edge cases as well.
  • I was able to solve one DP problem and was able to partially solve the remaining three. Even though there wasn’t any marking system given explicitly but it always good to attempt topic with higher difficulty level first. It increases your chances of qualifing the test. The results were declared after two-three days and total 14 students were selected for the technical interview.

ROUND 2(Technical Interview): The interview was on Microsoft teams. There was one interviewer and the interview last for 30 mins. He started by asking for my introduction.

  1. Firstly he asked me about my projects in detail. About technologies I used in my project and reason why I used that.
  2. Then he shift on to DBMS and asked about different types of keys their difference and significance. Then he asked about different types of SQL joins ,he then gave me SQL join query and asked me what result will it fetch.
  3. He asked me about Agile methodology, why to use it and how it’s better than traditional also name some traditional methodology (waterfall model).
  4. He asked me about features of Object oriented programming . He asked about polimorphism it’s types and it’s real time example also difference between static binding and dynamic binding.
  5. Then he asked basics of cloud computing as he belong to that domain.  I wasn’t able to answer all his questions since I wasn’t much familiar with that technology but he was satisfied with whatever I answered.
  6. Then He asked if I had any questions for him so as usual I asked about his experience working with fiserv.

ROUND 3(HR Interview): Those who qualified the technical round got a call for HR interview just after Half and hour. The HR last for about 15-20 min. She started by introducing herself and then asked me to do the same.

  1. She asked me to explain one of my project. She just wanted to know the idea and scope. she didn’t get into much detail.
  2. Then she asked what is your biggest achievement?
  3. Then about my strengths and weakness.
