I am having 3.3 years of expeience( specialist programmer L1). I am on notice period having 45 days still and i have offer letter from big4 of 14.4 fix and 1.4 variable. Then my stg manager told me he has already nominated me for L2 in jan quarter. My rating is OS . So he told me i will receive 50% hike and my current salary is 10.5 . He has also written me mail stating abt my progression in jan quarter and asking me to take back my sepration. What should i do?
