The selection process comprised three rounds, leading to full-time employment.

Round 1: Online Test

The online test was conducted on a platform (possibly Mettl, based on similar experiences) with webcam monitoring.

• Aptitude: Consisted of very easy aptitude questions.
• Technical MCQs: Covered C, C++, DBMS, OS, and Networks.
• Coding Questions: Two coding questions were given.
  1. "Suppose there is a 2D matrix. Find the transpose of it and multiply the original and the transposed matrix and output the result."
  2. "Rotate a given 2D array by 90° clockwise or anticlockwise based on the flag (0 or 1) given - 0 for clockwise and 1 for anticlockwise."

  Shortlisting was possible even if only one test case of one coding question passed, provided aptitude score was good. 33 candidates were shortlisted.

Round 2: Technical Interview

The questions asked were:

• OOPs Concepts: "What are the concepts of OOPs?" and "Write a code in any language you are comfortable in to describe the concept of OOPs."
• Code Discussion: Questions related to the written code, specifically about inheritance: "If class demo1 extends from class demo, and if we write demo d=new demo(); demo1 d1=new demo1(); Then can we write d1=d and why? Can we write d=d1 and why?"
• Computer Architecture: "Do you know anything about computer architecture?" (Candidate mentioned studying it in 3rd sem and not remembering well, then asked about registers).
• Operating Systems & Data Structures: Since OS and DS were mentioned as subjects of interest, questions were asked about virtual memory, segmentation, paging, and page faults. Also, "How will you implement a stack? And then what changes will you make to implement a queue? And what's the difference between queue and stack?"

Round 3: HR Interview

This round included standard HR and behavioral questions:

• Background: Year gap between 12th and engineering.
• Personal Attributes: Strengths and weaknesses.
• Technical Preferences: Which language are you most comfortable in? Have you done anything apart from your course in that language?
• Motivation: Why choose this stream/branch? Do you plan to do higher studies? Why pursue a job directly after B.Tech?
• Behavioral: What's the biggest risk you have taken till now? What are you passionate about? What are your hobbies?

5 candidates were selected for full-time employment after this round.
