Hi Suraj, It is great to see that you are interested in Management Consulting. I am not sure of your background, so I will try to get into as much depth as possible.
If you are trying to get into management consulting roles directly after graduation, you can apply for entry-level roles at firms like Mckinsey, Bain and BCG and the BIg 4 firms. For getting into these firms, you need to have good academic credentials and a stellar resume.
Once you clear the resume screening round, the interviews will be conducted where guesstimates, case studies and puzzles will be asked. So, if you want to learn something start with guesstimates and case studies. Case studies will also help in case competitions which give you very good experience about case solving and if you win some you will get good points on your resume as well.
In case you are looking for front end consulting roles, then MBA from Tier-1 B-schools always helps.
