I've read other posts on the same question, this instance is a little more specific.
I live in San Francisco and was contacted by an Associate Account Manager at Collabera for a role in San Francisco. After an initial screening the associate shared the Job Description at a reputable organization (UCSF) and arranged for a video interview with the 2 managers of the team this role would be a part of. Following this interview there was a take-home assignment. Submitting my assignment was the last correspondence I had with the organization looking to hire.
This morning the associate from Collabera called and told me that they want to extend an offer. I said that's great and I would like to know more details about the offer but the associate told me they first needed confirmation that I am still interested in the role before proceeding with the on-boarding.
The associate follows up the phone call with an email asking me to provide my SSN, DOB, Full Name, and Address. I asked for further details, specifically on benefits and compensation, but the associate's reply was that I must first provide this information before proceeding with the on-boarding. Once on-boarding begins, I will receive paperwork which will outline the details of my contract as an employee.
1) Should I give the associate my SSN or is this a concerning situation?
2) Can I still negotiate the terms of my contract once beginning on-boarding or is this something done before on-boarding?
