Once you qualify in INET you will be shortlisted for SSB and if you qualify in it you need to go for medical test.And if you pass in all the test and manage to be in the final merit list you will be given training in INA, Ezhimala.After successful completion of training you will be commissioned as sub-lieutenant.And the time depends on your performance.SSB is the toughest interview and not everyone will get through it.Some will qualify in it in the first attempt and some other will qualify in their tenth attempt.So if you work sincerely and prepare for it you can get through it in the first attempt.It requires a lot of determination and dedication.
