Company verification

Hi my name is Edwin, 

I'm trying to get hold of you HR department in the purpose of verifying if you are connected to/or a company officially affiliated with TELUS. I saw a post at LinkedIn for Media Search analyst. I on my first stages of my application. i passed the initial screening and now they are asking for Identity verification. I just want to make sure that this company is legit and I'm not putting my personal information out there. Here is the name of the company - TELUS International aka TELUS Digital. 

Hope to hear from you soon 

Thanks

Edwin
