Some companies don’t see privacy as security. They want to know your background, when you punch in/ punch out, if you’re the type of person to leak secrets over the “dark web”.
Some also don’t believe in privacy at all, they believe in contract. When choosing a platform they want to know if they can sue them for breaching an NDA.
I did not receive an offer from that specific interview but yeah, I admit it was odd and didn’t inspire trust so I wouldn’t have accepted anyway.
30 years ago was 1994, the internet was quickly becoming a thing and if you would have told them that companies would eventually offer extra services if you chose to store your data with them, they would have believed you because that’s how the banking system worked for centuries prior.
