Hello Aspirant

In order to become an English to Hindi to Bangla (language) translator, you need to be well-versed in all three languages. I'm assuming Bangla is your mother tongue, so you will be proficient in it at the native level. For Hindi and English, there are two ways- you can either have a degree in these languages (mind you, not the literature, but the language or the linguistics part) or do a certificate course with at least C2 or C1 proficiency. Only then any company or a government sector would be willing to take you because they need proof that you are good in that language at the native level. Translators are high in demand in today's world of globalisation and the pay as well is really good. All the best!
