      Application

      I applied through university. The process took 2 days. I interviewed at Ecolab in Aug 2025

      Interview

      First, we had an OA test containing basic aptitude questions. Later, people who scored more than 50% in OA had to take up the Technical test which had 3 DSA question, 2 of which were easy level and 1 question was based on strings which was of medium level. Students who clreared the test had an interview the next day. I was asked to introduce myself, and a few DSA questions were asked based on strings and arrays of both medium and easy level, and even situation-based questions were asked. The interview was about 30 minutes. I was qualified for next round which was HR round, it was for 15 mins. I introduced myself, and the HR asked me about my college, cgpa, extracircular activites apart from college, what I was looking for in that company, and basic HR questions.

      Question 1

      They asked me what I was looking for in this company, whether job safety or money. This was asked in both the Technical Interview and the HR round.
