Hello Thomas,
Well, it depends on the Institute you are interviewing to. You need your Higher secondary school certificates like leaving certificate and passing certificate. You also need Migration certificate, if any. Domicile is also required. Health certificate, Marklists and other Identity proofs are asked. You could also keep caste certificate, in case if asked but probab;y its not asked. But be ready with everything for the best.

BEST WISHES!
