I have worked for the same supervisor for the last 3 years, since I graduated from college. I do not want to inform him at this stage that I want to leave the company to go to business school since we are a small company of 4 people. I also can't ask anybody I work with since my supervisor will get to know this.
Now my question: How will the business schools see it if I submit one reference from my former supervisor for whom I worked during a 6 months internship in 2001 and one from my former professor who became a kind of mentor for me during the last 5 years?
Is that acceptable? Or do you have any other recommendation whom I could ask?
