Pros

“We have been with Zinc for 2 years now and won't look back - it gives both the TA and HR team transparency and regular updates and any issues that need to be addressed.”

Jed S.

Talent Acquisition Manager

“Zinc has been a great addition to our TA arsenal, its simple and easy to use and most importantly quick and compliant!”

Jed S.

Talent Acquisition Manager

“There are less options available to choose in the qualification check section for example: if any person with whose highest qualification is 12th standard, then what option he will choose it's a bit complicated.”

Vishal K.

AML KYC Analyst

Pros

“days later nothing so asked for a refund they said same thing, only way to refund me was to provide my name ,birthday, and address so they know that the refund is going to the right person. ”

Che H.

Technician

“A great service to offer our customers (Landlords and Property Management companies) as well as an ID verification system that we use internally to mitigate fraudulent accounts.”

Jodelene W.

Director of Operations

“When you recruit contractors internationally, it can be impossible to find a service that helps with document verification and background checks, no matter what country we are working with.”

Ronnie B.

Chief Business Officer

Cons

“The UI did not bring me back to the main menu where I could see the remaining items in the background check each time.”

Chris M.

Engineer

“Something that could be improved is the reference check option. When details are entered and a mistake is made, there is no option to edit the details entered and one would need to reach out to Zinc to have this updated, this could possibly delay the process.”

Carlin F.

Merchant Support Analyst

“Education check wouldn’t allow me to choose an exact date (DD/MM/YY), just month and year, and then it shows as a discrepancy when institution confirms the details.”

Tymon R.

Product Developer

Cons

“This doesn’t work for Quebec residents. And after finding out it doesn’t work, they reply this message”

Kemal S.

“Too many bugs in the system, they take too long to answer a support question or FUP in anything, no one really knows what to do in a situation.”

Carol C.

OP Manager

“Its a terrible expensive experience with no customer service and its frustrating.”
