Church & Dwight interview questions

1st round is online interview with hiring manager, then given a task to work on for 30 mins presentation in the 2nd round F2F interview in their office together with hiring manager's manager. They are very friendly and interested to know more about me, and I received a rejection email with detail feedback in few weeks.

1 hr call, then meeting with managers. The interview is very laid back, focusing on behavioral questions. No need to over-prepare, just be confident and conversational. If I could go back I would try to be more conversational.
