Are you aware of some of the cons of becoming a dermatologist?
As there are in any medical specialty for physicians, Dermatology comes with its own set of negative stigmas. Your interviewing team expects their resident to be there for the long haul, through thick and thin. This question will assure them that you are aware of the downsides of the profession that you will likely begin to experience during your training with them.
While things like long work days, work-life balance, and sometimes repetitive and stressful work can be considered downsides of a Dermatology practice, the good far outweighs the bad, and you hopefully can convey this to your residency interview team. It's okay to talk about what you feel may be the top downside to pursuing a career in Dermatology as long as you are aware of it and have a plan for negating it.
"Yes, I'm fully aware of the stress and long work days that can come with Dermatology residency training and practice. I am focused on making a difference in the lives of others. I have always been a hard worker, willing to put in any time and effort. Because I want to focus on clinical practice and research activities one day, I never see myself getting bored with the work."
"Every area within medicine can have challenges. While I do not necessarily view them as "cons" to being a dermatologist, I think something that may be challenging for me is guiding patients through treatment of chronic diseases such as eczema, psoriasis, or hidradenitis suppurativa, for which patients may be expecting a cure. I hope that in such circumstances, I can use my communication skills to explain to patients that while there may not be a cure, it can be possible to work together long term to achieve good control of their disease, and that with time I can build trust with my patients so we can find the best treatment regimen with them together."
