Merck Sr. Scientist interview questions

They came to our department and interviewed several grad students and postdocs. I gave a 20 minutes presentation and they asked questions related to research and some behavioral questions. And then they talked more about life at Merck and gave me the chance to ask them more questions.

He asked to prepare 15 min research talk related to PHD work, and he asked two research-related questions and two behavior questions. Seems like he didn't interest in the topic
