Hello,
Your post does not elaborate why you have only 6 months expereince when you completed MBA three years back.Was this due to marriage or other family responsibility?
Secondly,why do more courses when you already have an MBA.Courses will be useful only when you have work experience.MBA is enough to get you started and grow in your career.
There are many opportunities available within HR e.g.Recruitment,Payroll,Compliance,Employee Engagement,Training etc.
Hope you find this useful.
