I just called a hiring manager to see what the status of my application is. He informed me that I made it to the next round, but that his concerns about hiring me stem from the fact that I have been self-employed for the past five years, and he is not sure how I will settle into a strict 9-5 job where I have to answer to other people. What is the best way to address his concern during the next interview?
To some extent, the best answer to this stems from your own thoughts on his question. Why do you think that shouldn't be a concern for him? For instance, maybe working for yourself has given you a ton of insight into the burdens and challenges of being a manager, and you expect to be especially sensitive to and empathetic about that once you have a manager again. Or maybe you'd absolutely thrilled to work a 9-5 schedule, after years of having to work at all hours to drum up business for yourself, and can't wait to get back into a more traditional routine. Maybe you're more business-minded than ever after being in a position where you were entirely dependent on your own efforts to generate income.
Basically, the employer is seeking to make sure that you're not going to have problems accepting someone else's management and management style, and that you're not going to realize that you hate the switch after a few weeks on the job.
How do you feel about having a boss again, and working a more traditional schedule in a more traditional setting? Your answer lies in there.
