Standard questions about yourself and technical chemistry questions and synthesis. Not easy but doable if you know your name reactions. All in all very friendly impression. 2nd round onsite with a CV chat and synthesis of one large druglike molecule. Also some more mechanisms and name reactions.

3 rounds of interview : 1. general knowledge of organic chemistry 2. white board presentation of phd work in front of team leaders 3. 1 on 1 with management team overall pretty standard interview with some expected questions and some less expected. good to study
