Dear Aman, if you are asking that whether Executive MBA is a good career option or not, then I will say a big 'yes'. Executive MBA is really a high valued and demanding course in today's management market. But, in order to get admission in Ex-MBA, you must have at least 5 year of work experience at Managerial level. Aman, I am not sure that even IIMs offers the post-graduation course in Ex-MBA, but I would suggest you to go for FMS-DU (Faculty of Management Studies - Delhi University). I hope you are well aware about it. Its fees is quite low as compared to other institutions and placement index is significantly high enough. If you did well throughout the tenure of MBA, you can easily fetch a Rs. 25-30 LPA job (as per last year), with a designated post.
Hope you finds this helpful.

CAT is an entrance exam for more than 160 management institutes across India, including the 20 IIMs. The online CAT exam is conducted every year in the months of late November- early December. The CAT result is usually declared in January every year. The GD/PI rounds typically takes place from February to May. The academic sessions begin in the months of July-Aug.
Right time to start CAT coaching to get admission in IIMs Pre-final year students.
The right time to start preparation for next year's CAT exam is in pre-final year of graduation (3rd year of engineering or 2nd year of 3 year graduation course). These students can join TIME coaching center in a super long term CAT classroom batch. This will give them adequate time for preparation. Since they will be preparing for almost one and half years, they will be able to crack CAT exam by preparing for 1-3 hours every day. The only thing that needs to be ensured is to stay motivated and constantly prepare for the entire duration of the program.
