I am working in company 'A' in BPO domain with 2 years exp and I got an offer from company 'B' as a fresher in IT domain but in the new company. I have to join within one week. At the same time they did not release me immediately. In this case, can I drop the paper in company A and at the same time join company B. if I do it it will create any problem in my PF account (or) if that works.
