Is my ctc ok ?

8-10 years of experience fetches around 1cr. 15 years should fetch you around 1.4 + cr.

Very low. Should plus 70.

Working as what? 15 years means should be leadership semi leadership. In which case. Katt raha hai. Either aapki quality ka, ya aapke CTC ka.

it is not very low. assuming you are sse and nees to move to staff. not everyone moves ro staff or principal in faang. it's a broader topic to solve. pleanty if sse folks in similar bucket in such companies. Moving to a 65 base could be the next thing in sse/entry level staff/Principal. Obviously perf bonus and stocks are tied to level and base.

igso, experience seems good
