After eight years of IT experience, do you suggest I go for a master's degree or first try for a few months to see if I can get a job directly in Ireland/Netherlands?

With eight years of IT experience and a current salary of ₹15 - 25 lakh per annum, you are well-positioned for senior IT roles abroad. Given your profile, it is often more advantageous to first explore job opportunities directly, especially in countries like Ireland and the Netherlands where experienced IT professionals are in demand and can earn competitive salaries.

A master's degree can add value if you have specific goals such as switching to a specialized field or if you find that job opportunities are limited without it.
