Sorry, but no. Banks usually need candidates to have at least a graduation degree — that means 10th + 12th + 3 years of college in any stream (like B.Com, B.A., B.Sc., B.E., etc.).
If you only have an ITI qualification, you won’t be eligible right now. You’ll need to complete your graduation first, even if it’s through part-time or distance learning, before you can apply for most bank jobs.
