Trending @Wipro; Promotion Scales

Hi, I have been on B2 band and now maybe getting promoted to B3 soon in next quarter. Can anyone tell me if my salary will be hiked (standard percentage 10-20-30%) Or will it be with respect to the slab that a B3 level has in Wipro.

Can anyone tell what is the decided slab for B2 and B3 in Wipro ?

Thanks in Advance
