  • Q3. Third Round: HR Round

Interview Preparation Tips

Interview preparation tips for other job seekers - In the first round, the question was to draft test plan for Computer System Validation plan. It was a good example of a real life scenario. It really took me by surprise but tested us on how to relate our work to such real scenarios.

Second round was technical and tested if our work experience matches their requirements. Also, questions on activities that will be performed as part of the role.

Third round is HR to understand our expectations on remuneration.

Based on my experience, I feel that the Organization expects us to be well informed about the pharma domain and technically as well. This is for testing roles.

Questions were realistic based on what we had done and will do if selected. Discussion did not go off topic and it was a healthy forum to share our views.

Of course, I am happy to share this since I was selected and joined the Organization but would have done the same even if weren't because the whole process was good and necessary.
