From my very experience, the recruiter called me to pre-screen interview just to know a bit more of your background and then they will set up an interview date. For the interview, I guess the manager will be the one who’ll interview you. So they will ask you with some basic interview questions in English to see if you’re able to talk in English or not. Lastly, after all that, they will give you a test which you’ll provide English writing skills to them.
