The hours very they arent set hours, their is a lot of driving from client to client, and it on and off all day
Look into the company and what they offer, look for what qualifications they need for the job, be yourself, have good knowledge and know what your taking about
Is there a guaranteed number of hours per week? Is it possible to work fulltime hours?
Nothing is guaranteed, no workers rights so you can be dropped at any time for any reason without warning and without being informed why.
