One day interview. 1H with group leader to discuss typical HR questions 1H presentation 1H technical questions 1H situational interview Lunch with other candidates and members of the group. Everybody made me feel comfortable and it seemed to be a great place to work. The situational interview with HR was challenging. Take your time to think before answering and it is OK to use pen/paper. The technical interview was difficult - organic chemistry questions, inorganic chemistry questions, thermodynamics, analytical. Also be ready to answer how the combustion process works.
