It'z not off topic but a different answer if I write the event when I went to Navy selection centre where they told me to wait and I said, "I 've no time to wait" and then I cancelled the appointment.
Plz don't think me a proud or something as that time I hadn't received the appointment call but it was my sudden response as I travelled 25 kms fighting with the cold wind blowing that day.
This event reveals that It depends upon the circumstances and situation so if you 've no other good option to earn till the ce exam+result+appointment (app 2 years if you join cs) then you shouldn't leave the job Navy is offering to you. But if you have a heavy pocket till that time mentioned above then leave that. Looks Simple but I dun't know the situation with you so decision is upto you bro.
