Hello,
Since you are 29 years old and have completed a master's degree in Chemistry, you are eligible for several government job opportunities. You can apply for positions in research organizations, public sector units, teaching jobs, and central or state government departments. Some options include jobs in CSIR labs, DRDO, ISRO, chemical testing laboratories, state public service commissions, and assistant professor or lecturer posts in colleges. You can also consider competitive exams like UPSC, SSC, and other recruitment exams where a science postgraduate is eligible.
Hope this helps you.
