I'm currently working at an internship that started at the beginning of the summer. The internship was only supposed to last for the length of the summer, but my company decided to keep me and a few other interns to work part time for the fall semester. The company expressed that they wanted to keep us because we were good performers, and I accepted because I hoped it would streamline the process from intern to full time employee for next year when I graduate college.
However, I have since reconsidered and no longer want to work at this company after I graduate. Among other concerns, they push excessive overtime onto their full time employees, and that is the exact opposite of the workplace I want to be a part of. I have luckily been spared any hardships as an intern, but I expect that to change if I take a job with this company. Unfortunately, I have somewhat trapped myself since I have told both my boss and HR multiple times that I hope I can work there after I graduate.
I do not plan on bringing up this issue to my boss or HR (or anyone I work with for that matter), and I want to hold onto my internship until it ends in December. They start their college graduate hiring process around January, so I should be able to avoid questions until it gets closer to the end of my internship.
What reason do I give them for not wanting to work at their company next year if/when they setup an interview or ask me about it at work?
I don't want to point towards the bad facets of the company if they ask me why I don't want to return. I'm especially afraid of a face-to-face confrontation in which they might question my reasons further. How do I handle the situation?
