Got offered Nonhospital job but not sure what to do???

I was recently offered a job at a outpatient dialysis clinic and as being a new grad, I accepted it because I need the money. The training is about 3 months and its 5 days/week which means if I get a call from a hospital to interview, I won't be able to go.

I applied to 100+ positions in different hospitals around NYC, Westchester & Long Island and I know it takes time but pretty soon I won't be considered a new grad anymore (I graduated in Jan 2018). I been proactive with the Job Search and even went in personally to hand in my resumes to a few hospitals.

My question is, am I selling myself short by just accepting the dialysis job and not waiting it out or should I just take the job for now to gain some type of clinical experience and reapply to jobs again within another year? What would you do?
