111/999 call handler jobs - will this be useful experience?

I have recently graduated university (I have a BSc in Psych and an MSc in Developmental Disorders) and I am looking for jobs. Whilst I'm covered academically, I do not have any direct work experience yet (the closest thing I have is being a volunteer Welfare officer for a student society).

I have been applying to jobs for a couple of months now, but I have had no luck in getting any HCA or SW jobs in the NHS. I'm at the point where I'm applying to anything now, so I've applied for a job as a 111 health advisor and I've got an interview. It's quite a stressful job and you do have to deal with distressed people/people calling for mental health reasons. My question is, will this be useful experience? I won't be staying in the job for more than 4-5 months so I will be looking to move on fairly quick - will this job help me get other NHS jobs?

I'm also interested in hearing anyone's general experience with working 111/999 jobs! Thank you for any advice!!
