The interview process consisted of 1 coding round and 3 PE interviews.

Out of 200 students, 20 were selected for the interviews. Interviews started the next day and ran the entire day.

The interview process was boring. After waiting 2+ hours, the interviewer asked me about my internships with some basic questions.

Then, he asked me three questions on data structures and algorithms:

• The first question was "running length medium." I solved it easily.
• Then he asked me about heap sort and wanted me to write proper code and an explanation. I explained briefly.
• He asked me the second question, which was about the next greater permutation of a given integer. I was stuck initially, but he guided me to the solution.
• Then he asked me the last question, which was about a binary tree. I don't actually remember the exact question.

After waiting for 30 minutes, the second interview was about proper DS/Algo. They asked me 2 questions which I was not able to solve.

After the interview, I was not selected for the process.

What was the time period of the internship, and why did I choose that particular internship offer?
