It started with an online test at hackerrank which included the various quants and aptitude based questions. The second round was the technical interview which included puzzles and questions from OOPS and operating systems mainly. Other core computer science subjects like computer networks and DBMS were touched upon.
Overall experience of the interview was great. I was able to answer all questions correctly including the puzzles.
The third round was the case study round and it took place just after 15 min of second round. It was a general case study round where we were asked to answer some scenario based questions.
I moved to fourth round which was a stakeholder round which took place next day. The questions were mostly scenario based.

Question 1
How would you explain red color to a blind person?
I applied online. I interviewed at ION Group (Gurgaon, Haryana)
Interview
The initial interview process was in 2 parts: technical and case study.
The technical part contained a few questions based on my resume and a few behavioral questions (may vary depending on the interviewer), and if you pass that, you head on to the case study part. The case study part can be solved if you use your common sense and creativity. Overall, it was a decent process.
