Certification

For job opportunities (to get preference for interview and placement), no, but the learning from IGNOU is really good, you may apply those principles learned in the day to day business scenario and the same will improve your skills. However, if you are a fresher, there is little help you will get from it unless your employer wants that kind of certification.

Instead of certification, please do an internship in the related area where you want to make your career and participate in the organizing committee of your college festivals in the coordination, event management, budgeting, etc as it will add more value.

AIMA, means All India Management Association, New Delhi, which is a body that promotes management programmes across India. AIMA is also a recognized body, but not a university. It is like an institution. You can prefer. All the best.

Dear Monika,
A break in one's career can be a challenge specially in the beginning. Certificate course in HR might not help you much unless you have anything specific in your mind such as HR analytics or payroll etc. Instead brush up your knowledge and start applying, there might be some corporate who would like to hire. You can join recruitment consultancy to begin with, later on can try moving to corporate HR.
Best wishes.

You are advised to do a short-term course on computer hardware maintenance and repair so that you have good hands on exposure on PCB repairs. This knowledge will be helpful in circuit design and its practicals.
