Coding Round: The very first round was an online test conducted on It contained two coding questions, randomly selected from a lot of several questions, to be completed in 1 hour. The two questions which I received were:

  1. Frequency of a substring in a string
  2. Minimum lines to cover all points

After a couple of days, I was informed that I was shortlisted for the Interview Round.

Round 1 Technical: The technical interviews were held on, which supported both the video conferencing and codeshare features. I introduced myself to the interviewer on being asked. Then, the interviewer started with a couple of coding questions as mentioned below.

  1. Find whether an array is subset of another array using Map
  2. Trapping Rain Water

I suggested an optimal approach for both the questions, wrote the codes on the codeshare platform, and told the time complexities, which satisfied the interviewer. The interviewer went forward with some OOPS related questions on Abstraction and Inheritance. I was even asked the logic on some SQL queries, on which the interviewer was contented with my answer.

Technical Round 2: After being shortlisted for the second round of technical interview, the interviewer asked me to introduce myself. Following this, he asked me to explain the project that I did in the last summers in a training program. After this, he asked me a couple of coding questions.

  1. Segregate 0s and 1s in an array
  2. Detect loop in a linked list

I was asked to code the first one and tell the approach of the second problem, both with optimal time and space complexities. After this, the interviewer asked some questions on OOPS (Abstraction and Encapsulation) and Operating Systems (Virtual Memory and CPU Scheduling). I was confident in both the topics and answered the questions that satisfied the interviewer.

HR Round: HR Round was held on the same day after a few hours of the second technical round. The HR started with her introduction and asked about me. Then, the HR asked me to explain my best project, followed by some usual HR round questions.

  1. What is the toughest decision that I have made in my life?
  2. How was my recent internship? Any problem that I faced during the course of my internship?
  3. Explain about the time when I had a conflict with my peers in the organization of an event in the college fest and how did I resolve it?
  4. Why do I want to join Reliance Jio?

The HR seemed contented with my answers and closed the interview asking if I had any questions for her. I had none.

The results were out the next day, and I was one of the few selected candidates.
