Common notice period norms
In India, notice periods for IT roles are commonly 30, 60 or 90 days, depending on the company and seniority. Many large services firms use 60 to 90 days. Some employers allow buyout, where you or the new employer pay to shorten it, while others only allow early release at the manager's discretion.
In the US, two weeks is customary for most at will jobs, though senior roles may give more. For remote roles with global companies, recruiters often expect shorter timelines, so explain your Indian contract terms clearly.
