1. Finance: As you said you are from a Commerce background. This can be your strength area, as you might have studied finance in a lot details than other students. If you go for finance you will earn quite a huge sum of money after your MBA. Generally it's the finance and banking sectors that offer highest packages. One has to be very good at dealing with numbers and the analytical and numerical aptitude has to be of highest levels.

2. Sales and Marketing: If you are interested in sales and marketing then this is for you. You need to be passionate about consumer behavior, their buying habits, how do advertisements change their decisions and things like that. You will have to gather the data and process it accordingly in order to come to the conclusion. This stream requires a mix of analytical and people skills to effectively produce the desired results.

3. Human Resource Management: HR Management is for the professionals who are good in dealing with people and want to manage the human resource part of an organization. It is not as easy as it appears first. it takes years of practice and learning to work and effectively communicate with the people from different backgrounds and different thought processes.

I have briefly explained about the three main branches of MBA. Similarly you can apply the same logic on others. Please note that it is highly recommended that you go by your interest and aptitude levels. If you are not sure about your strengths and interests, in that case you can take psychometric assessment tests too which will help you in figuring out the right fields for you.

Thanks for choosing MeraCareerguide and writing to us. I will base my answer in two ways, one at academic level and the other at work level.

1. First at an academic level, you can finish your schooling with any subject that interests you. Ideally if you are studying at an International board like the Cambridge Curriculum, you can study Business studies or Management subject in your AS and A level (11th grade and 12th grade). If you are keen in only studying Human Resource Management and doesn't want to do any other degree, you can consider studying a Bachelor of Business Administration degree (BBA) with specialization in Human Resource Management. Studying BBA with HR as your major specialization would prepare you well for an entry level job. In your case, a Commerce degree is good too. Additionally you should understand that Human Resource Management is a people oriented subject. You need to have strong people skills to success in this field. Not just getting a degree will actually help you in job. Developing yourself with all those essential people working skills like communication skills, listening skills, presentation, negotiating skills, effective writing and relationship handling are highly essential. With a BBA degree in HR, you can work as a Management trainee or entry level HR jobs. If you further want to develop your knowledge on Human resource Management, you could also continue to a Masters or the Professional degree like the MBA. Again, in your MBA, you have an option to major in Human Resource Management. But studying an MBA degree is appreciated only after gaining a considerable amount of work experience. Normally reputed B-Schools encourage students to apply for an MBA only after gaining a minimum of three year work experience.

2. At work level, a HR role has many internal branches. It involves with:

• Selection and Recruitment: You source suitable candidates for the job vacancy, invite them for an interview and handle the interview. People involved in this area of recruitment are normally designated as Recruitment Analyst, Recruitment Manager, Resource Manager, Talent Manager and so on.
• Learning and development: This division is quite popular in India in the recent years. It is known as L&D department in short. This department develops training materials and handle training for employees to update their specialist skills for their work.
• Employee relations: Handling queries and solving problems between employees. It further adds to grief handling.
• HR administration: Handles the compensation, benefits and pay roll of employees.
• Organization change and development: This is a Strategic HR role where only senior professionals are involved. This senior most department works for improving the over all employee performance and the company's profit growth by utilising its very own man power. They handle merger and acquisition, succession planning, diversity and inclusion and industry relations. To move into this department, a considerable work experience in other fields of HR is essential.
