To set up the question.
I was offered a position, and it is contingent on a successful background check. I have a solid educational and career experience background. I recently finished grad school, and while finishing my thesis, worked on my own entrepreneurial project, a website (that deals with dynamic data management), which I developed with a partner. In addition to building it, I shopped the website to investors, potential partners, and worked to find people to test the product, but have never gotten to the point where it was validated as a business and therefore it made no sense to incorporate, charge people, etc because we were more interested in development and functionality than spending money at the time. It is scheduled to be beta tested in use soon at which point decisions like that would be made.
The existence of my work is verifiable. The website functions at a high level, and I have plenty of proof of the time, conversations and effort put into the product. The website was discussed in the interviews, my responsibilities have been represented correctly, and I did not claim to have collected a salary from the website (additionally, the salary offer from the hiring company has already been submitted). The long and short of it, I've been upfront about the project and never represented it as a functioning business, I did however include it as part of my work history, because it is.
So the issue I have run into is with the background check. They have their instructions to verify, and they have their limits on what they can accept as verification. Since this was included as part of my work history, its something that they wanted to look into. They reached out to me for more information, however where the website's current development is, doesn't fit into (incoproration, w-2, 1099's, etc). They are also unwilling to speak with my development partner. Due to this and based on my conversation with them, they are likely to report it as "unable to verify."
I'm wondering what the correct process is to handle with the hiring company's H.R.? Like I said, I haven't hid anything about the website, and in my application, cover letter, resume and 3 rounds of interviews, represented the work as it existed and was performed. To clarify, I explained clearly in the interviews that it was an entrepreneurial project and that unfortunately we hadn't found investors to grow the project as I had hoped. The website and its functions are relatable to the position. I include it as part of my resume because its relevant to my skill set and understanding of the field I work in.
I know that it is likely to be the only checkered mark on the background check, and I'm wondering what I should do to address it to H.R. or the hiring managers.
