Question about Babel Audio - Spanish Bolivia - How long does the reply take?

Hello everyone, blessings.

I'm María from Cochabamba - Bolivia, I applied to Babel Audio as a native Spanish speaker through AITraining.jobs.

I'd like to ask those who have already been through the process: How long did it take them to reply to you after applying? What is the interview like? Is it in English or Spanish? Can you work flexible hours?

I really appreciate any information.

Thanks, María O.
