Selection process for getting admission into a good Business school

I want to know the selection process to getting admission into a good Business school.

Reputed Business schools admit students on the basis of a 3 stage selection process that includes a written examination followed by a group discussion and personal interview. Generally written examination are of two to two and a half hour duration with multiple choice objective questions which covers various aspects of aptitude tests like Basic mathematics (Quantitative Analysis), English language (Verbal Analysis), Reading Comprehension, Data Interpretation, logic, general knowledge etc. Getting a good score in this written test is not enough to assure the seat. There will be group discussion (GD), team-building task and personal interviews (PI). Students are admitted, based on rank lists prepared on the performance in the written test, GD and PI. The marks that you have got in graduation level are also considered by some institutes. Extra-curricular activities and qualifications like work experience will be an added advantage to the candidates but are not compulsory.

Common Admission Test (CAT) conducted by Indian Institute of Management (IIM); Management Aptitude Test (MAT) by All India Management Aptitude Testing Service (AIMATS) New Delhi; Xavier Admission Test (XAT) by Xavier Labour Research Institute, Jamshedpur (XLRI); Joint Management Entrance Test (JMET) by Indian Institute of Technology (IIT); ATMA by the Association of Indian Management Schools (AIMS) are the major national level entrance examinations for admission to management courses. Even though these exams are conducted by the respective institute for their admission, its scores are widely accepted by many of the Indian Business Schools.

MAT exams are conducted 4 times a year while all the others are held once in a year. Certain Business schools and universities conduct their own entrance test and some of these include National Management Aptitude Test (NMAT), Symbiosis National Aptitude (SNAP) Test, Open Management Admission Test (OPENMAT) by Indira Gandhi National Open University (IGNOU), Written Admission Test (WAT), IBSAT, CEMAT etc. All these exams follow the same syllabus and students can write 2 or 3 of these, so that they can apply to multiple institutes.
