Supervisor's behaviour changed after I decided to move to industry As any other late-stage PhD student, I am applying for jobs. But I noticed that my supervisor's behaviour changed a bit after she heard that I want to go to industry, although she has been a great admirer of my work and encouraging me to pursue my academic work. I was wondering if I should be concerned about this or just let it go?

The story: I applied for a few academic positions and my applications were not successful. So, I decided to apply for some non-academic jobs in the industry. Fortunately, my applications received good attention in the industry and I was invited to a few interviews. Particularly, one of the companies responded very quickly. They have even called my references immediately after interviews. I felt that my supervisor's behaviour has changed ever since I told her about this. She saw me on the campus and coldly told me: "I just answered a phone call for you.".

Meanwhile, I received two interview invitations in academic positions, and the interviews went quite well. But the areas are not much relevant to my previous research, so, I am a bit hesitant about them (although they are really excellent positions). Besides, the industry offer is much more generous from the financial aspect. 

I was wondering if I should be concerned about my supervisor's behaviour or it is a normal thing? Have I done something wrong?
Most people would not consider you to have done anything wrong in applying to industry - but your supervisor might, because some academics consider non-academic careers to be "second-best".

However, are you sure that the change in attitude is because of this? Could it simply be that you put your supervisor down as a referee without telling them about it? That might be considered rude, leading to surprise at getting a phone call about you.
