First of all, you have to check your age limit for appearing in banking and SSC exams. As per the information the upper age limit is 28 years for appearing in Clerical post and 30 years for probationary officer (PO) posts in bank. And, you are 29 years old so you can appear only for bank PO exams. As far as SSC exam is concerned you can appear only for SSC CGL exam because it upper age limit is 30 years while some posts have 32 years as age limit.

Also, any graduate candidates can appear for SSC CGL and Banking PO exams so you are eligible to appear for both exams.

you should go with the bank exam i.e IBPS specialist officer because it is open for people who have done a bachelor degree in IT, law, marketing etc.On the other hand, SSC is having the post for IT but it is open for all and it won't benefit as it doesn't consider a bachelor's degree in IT essential.if you with SSC examination your degree will benefit in practical sense i.e in interview where you can explain the things
