Initial interview was with HR. It was nice, she makes you feel at ease and conversations are light. She didn't seem to judge you at first glance. Basic questions, "tell me something about yourself, future plans, how did you know the company, etc." You get the picture. Then some more personal questions, those that doesn't invade your privacy, like your hobbies and interests. Basically she wants to know who you really are. Next is with the supervisor you will be under, they're quite nice also. You'll know they will be easy to work with. They will ask about your experience (if any) and will give you a summary of the work you will be handling.
