You should not go for an interview cause the place is horrible place to work and they'll just let you go after 6 months anyways.
Hours are set, odd shifts some times but manageable if you ask around you can swap and they have a system for this but won't always work in your favour and be ready to book holidays well in advance
Does Voxpro require pre-employment background checks? What kind of background check does Voxpro do and how long does it take to complete?
Relevant experience is desirable and is taken into account during interview process in my opinion.
