HR have no understanding on how they should be compliant with. Standard email with no feedback getting sent but no way of finding out what went wrong. As they are a so called company it implies that they are hiding things and maybe the lockdown might find out what they have been up to. Also turning people down for a job does not state that their details are held secure as I imagine they are potentially selling on mobile numbers or emails direct to third party as no confirmation that the details are safe.
