Interview Preparation Tips
Experience: We were asked to solve a questionnaire containing 25 questions based on logical reasoning and basic mathematics. We went to the test center in their recruitment center where there were many desktops for the candidates to sit and give the test. At the entrance, they checked the letter we got from them to authenticate us.Then they gave us a login ID and password. Exactly when the test started, the portal became active and we were asked to enter the credentials. I completed the test in half the time as it was pretty easy and straightforward.
Tips: Practice simple aptitude questions for greater speed and accuracy.
Duration: 1 hour
Total Questions: 20
Round: Group Discussion
Experience: Ten candidates who were shortlisted from the written test attended the group discussion. The topic given to us was fairly simple and lucky for me, I used to work as an anchor, and being a strong feminist person, I had a lot of valid points to put forward. I was the one to start the discussion, and I felt I was the best speaker there. The topic was something that I follow regularly, yet I came across a few unique points from the other candidates.
Tips: Improve your English speaking skills. Be assertive and speak concisely.
Duration: 15 minutes
Round: HR Interview
Experience: The interview basically revolved around this one question which had a few follow-up questions, such as who all are there in my family, what are my strengths and weaknesses, and why am I fit for this job.
Tips: Be confident and honest about yourself.
Round: Technical Interview
Experience: I tried to be as calm and confident as possible during the whole of the interview
