Hi Sir, I am here to look for a career advice. I do have total of 5.9 years of experience in IT which includes both manual & etl testing. My current ctc from a reputed MNC is 5.38 and I do have an offer for 9, but they're asking me for written confirmation that I will stay in this company for 1.5 years. What should I do here? Should I accept the offer or negotiate on bond period. Any advice that you can provide?
