Business Management Studies in UK

UK is perhaps the best destination for students from India to pursue their Masters. Even the test for English is also waived off for many students from India. There are special counselling agencies in Delhi and big cities which offer advice about different aspects of studying / scholarships / living / post study work permit, etc. I will advise you to contact them further for detailed information.

Yes, you can get job in India.

Hi Mudit,
The only exemption you can expect is an IELTS or TOEFL waiver, since you have completed your Masters from UK. GMAT or GRE is a mandatory requirement as applicants with high work experience of 10-15 years can expect GMAT waiver.
It is quite difficult for international students to be exempted from such requirements. However, you can still write to the university and have a chat on this. Good Luck.
Best,
Anjali
