Does Christ University offer good placements even to students having no work experience? Should I do an MBA without work experience?

First of all, you will need to get admitted to Christ before you think of getting placed. For pursuing MBA from Christ, you will have to meet the eligibility criteria of securing 50% aggregate in your graduation and an aptitude score in CAT/XAT/GMAT/CMAT. Your class 12th marks will also play a role in your overall score card and also you will be tested on your performance in the GD/PI session. Once, you have secured admission, you will be given enough opportunities in Christ to showcase your leadership and management skills in terms of internships and organizing various events. So, yes you do not need to worry about work experience while taking admission. However, students with prior work experience will have an added point on their resume. I would suggest that you try to gather work experience before pursuing an MBA. Try to take up internships or voluntary projects as it will give you an edge as an MBA student.
