1 grade below senior manager/senior consultant would be 85k +/- 5k pa. of course this is about the median and expect some higher or lower.
average performing senior should have no problem with 95-100k pa. difference between an average performer and good performer can be as much as 20% more pa due to bonus (1-2mths more). and of course good performer would have maybe 6% increment whilst average 4%.
a few years back the ceiling of senior is 8.9k pm. this window moves every year and the overlap between grades is ~20-25%. a higher ranging senior could make more than a entry level ad on a monthly basis.
the salary range in
ida is quite transparent. the range is clearly indicated in the offer letter and every year's increment letter for your own grade.
