I have not worked with that company. In my first job, my BC was done by Hireright. It was quick and was completed in 1 week. For my current job, CARCO group did BC for me. This company asked too many questions and tried to do through check. They asked information like dad's name, grand father's name, mom's name and also the passport no. and nagrikta no. I do not know what they verified but it took around 2-3 weeks to get the clearance from them.

To expedite things I used to call my prospective HR asking if I can give 2 weeks notice to my current company, once in every 2 days.

If you don't have any criminal history then you should be fine. Just try to give pressure to HR to speed up things. Make up some stories about your current situation in your job and try to get clearance from HR.
