1. First, she asked about how I am and how my day was to make me feel comfortable. Then, she asked me to introduce myself. After that, she moved on to my resume, reading each and every line and cross-questioning me on almost all the hot topics I mentioned. Then she asked me to briefly demonstrate all my projects. She inquired about the difference between C, C++, and Python, what OOPs is, and then asked questions about strengths, weaknesses, qualities, why they should hire me, and what I know about ServiceNow. Finally, she asked if I had any questions.

2. This time, he started by asking how my day was, how I was feeling, and how the previous round went (I tried to remember the name of the previous interviewer). Then, he asked me to introduce myself and moved on to my projects. He asked me to show them if I had them on my system since I attached my GitHub link. So, I explained them line by line with the help of my Git repo. Since my project involved Sudoku solving using backtracking, he asked me to open and explain that part of the code and logic line by line. After this, he moved on to SQL, asking about joins and a query related to a left join under some extra conditions. He asked how, being from electronics, I came to the software field. There were also a few behavioral questions, similar to those asked in the previous round (three principles I follow in my life, hobbies, journey so far, am I satisfied, etc.). A few of my friends were asked easy array questions, real-world examples of graphs, how to transpose a table in SQL, etc.
