I'm an Italian new graduate who got an offer letter from a top American company.
They asked me to submit a form by a third-party agency to check my Background.
This was the first time I heard about a background check and I am very afraid I have made some mistakes and omissions in the Employers sections.
As a fresh graduate, my work experience in my CV are uniquely Internships, and University projects, an AIESEC Global volunteer experience and my experience as blogger (unpaid).
I thought as "Employer" only my internship employees avoiding the other experience listed above because:
In the university project I joined to a Startup to create a business plan for a startup challenge sponsored by my university, but it was without a regular contract.
Aiesec it was a volunteer experience in a School so I did not think it was a proper employer
Blogger, it just myself and I listed the skill learnings during this my hobby/ and sometime little job ( e.g. Digital Marketing, SEO etc)
I listed these experiences in my CV, but clearly explained the nature of each.
Now I'm afraid I have made terrible mistakes by not reporting those in the background check and I am very afraid to not get the job. I tried to tell this to the 3rd party agency but they always replied me with sort of standard email and seem they don't read what I say.
What do you think should I do? I want to contact the HR of my employer, do you think is a good idea?
Update.
I passed without problems the BC and they did not ask me anything more. My concerns were unfounded :)
