Very Detailed technical questions regarding the field I would've have been working in. For example, i applied to be a turbine engineer, fresh graduate. They asked me the process of the Rankine Cycle. In addition, they also asked a couple of troubleshooting procedures. The interviewer was very respectful, HR was also a treat to deal with. Overall good company, my best advise is to prepare for this interview from both the technical aspect and the general questions.
