Project Details urgent help?

[bkr_82_in]

$40 Billion product company. Full time position. I will be going for visa interview soon, will be working on product development team. More than 30 customer for this product. What kind of questions expected ?
They have given the product brochure, company overview document and job responsibility doc the same was submitted to USCIS But they have not given any project detailed document. Would it be a issue if asked. How should I tackle this situation.?

That is not a problem with such a big company. What you have been given is enough.
