The caller ID was legit, but I didn't trust it.
After a few questions such as business name and address I just said "I'm sorry, I'm not comfortable discussing this over the phone when you initiated the call" She resisted for a few minutes and then gave up. It was probably legit, but don't call me.
Also, PSA to anyone who's going to be hiring people that will be calling someone. The person at the call center should be a native english speaker because when it's someone with an indian accent or any other accent I'm going to be that much more skeptical. It sucks because I feel racist saying that, but the vast majority of scammers are have accents.
