h1-b visa transfer process, never entered USA.


I got my visa stamping done from company A in 2014 with validity till 2017. But I have never been to US. Now I have shifted from company A to company B. Company B has applied for transfer and I just got an email today from USCIS that the application is approved. So what will be the next steps? should I go for a visa interview again? Will the interview be same like the fresh application? Or is there any other way to get the visa stamped. what is the rejection rate for these kind of cases? If possible, please share some sample Q & A for these type of cases.
