What questions to expect from Skype chat with potential supervisor for a Masters in Neuroscience? I am applying to a Canadian University for a Master in Neuroscience. I have contacted a professor and asked for a place at his laboratory even though he only accepts PhD and post-doctorate students. However, he said that he accepted me as his student but wanted to have a skype meeting for us to get to know each other. 

I am a medical doctor and his area of expertise is more philosophy-oriented. I am not an expert in this area. My questions are: 


Will I be expected to have a well established research proposal even though I am a master student?
Are master students expected to have solid knowledge in the supervisor area even though they have a very different background? 
What are some questions a master student can expect from a skype meeting with his/her possible advisor?
Ok, my interview has already taken place. In case anyone has the same question, it was a very relaxed interview ( even though I was obviously very stressed). 

The researcher asked me why I chose to contact him, what I wanted to focus on ( based on his previous projects), when I would start, how I was going to finance my studies and how long would I be willing to stay at his laboratory, etc. 

I wasn't asked about neurobiology, physiology or any other scientific knowledge.
