Is it a good idea to do MBA after working as a software tester (2 years)? If yes, which field can I choose?

Yes, this would be a better idea. An MBA degree offers many professional, as well as personal, benefits. Whether, you work in technology, finance, management, marketing or manufacturing, it will open up opportunities for greater responsibilities, career advancement, and increased financial reward. F

Yes, MBA can be done at any point of the career. It will add value to your industry knowledge and of course a pay scale. But I'll suggest to do MBA only if you want to do it. Don't do it for the sake of high salary expectations. MBA from a good institute will be more effective.
