Very conversational, more informative on what position responsibilities were. Some questions on technical background and laboratory skills, if I had used HPLC, GC, DOE, etc. The interviewer wanted to know my interest in the position and allowed me to ask questions. I felt comfortable and helped me know if the opportunity was good fit for me.

It was more focused on letting you know what is involved in the internship and allowing you to ask questions. Not stressful at all and required only one interview with one person.
