I see your point, and that is indeed the case in some companies (or even roles within companies). I also advocate for keeping a separate work/personal phone.

However, being a background checking company, making phone calls is absolutely in their BAU remit. Upon submission of documents, they even state in their automated email response that they may call you for further information. Plus, they regularly call companies to verify employment information.

I got the distinct impression that they have a certain process, and they pay certain ranks not very much to simply follow that process. Any minor deviation from that playbook needs to be handled by a "senior", who is "empowered" to think and handle things like a regular human.
