It is simple to gain admission to IIM Bangalore to pursue an MBA. Apply for the common admission test (CAT), get a good percentile based on your previous work experience, and then pass the WAT-GD-PI process. Every year, nearly 2 lakh aspirants take the CAT. The prestigious 2-year MBA program at IIMB accepts only 400-500 students. That means you must outperform 1,99,500 other students or 99.75% of those vying for the coveted seat.
IIMB requires stellar academics in your 10th/12th/UG, meaningful participation in extra-curricular activities (even better if you have won some awards), and a zeal to give your best and survive the rigorous curriculum as you enter a daunting corporate life later. If you are a General Engineer Male (GEM), you must score at least 99%ile (assuming you scored 85-90% in your 10th/12th/UG) to be considered for an interview. Sometimes the cutoff is as high as 99.5%ile or higher. Because of gender diversity, General Engineer Females (GEF) have a few percentile points advantage. If you come from a non-engineering background, you can still get an interview even if your score is 90-95%. Although your percentile goal should not be based on your UG profile. To get the highest CAT percentile, you must give your all.
For CAT preparation, you must first understand where you stand. Solve any previous year's CAT exam to determine your strengths and weaknesses. Consult a coaching institute to determine whether you require coaching or if you can prepare on your own. The idea is to start with the fundamentals. After that, begin solving mocks. It is also more important to analyze mocks than it is to solve them. Determine your mistakes and try not to repeat them in the future. The trick is to look for incremental improvements in each mock.
When the CAT is finished and you have achieved the required percentile, it is time to start preparing for the WAT-GD-PI. Interviews for the IIMB will be stressful. They will run a rapid-fire round with strange questions, testing your ability to survive the rigorous curriculum while also verifying your credentials and experience.
