Is conversational English enough for work?
I found an interesting vacancy, but it requires English. And I really want to apply for this vacancy, but I'm worried that I won't be able to work well just because my English level is not high enough. What do you think? Is it worth a try?

Well, it's definitely worth a try, I think. If they don't specify the level of English they require, then you may well fit in with the level you have. And in general, there are no problems with starting to learn business English now.

By the way, that's true, and now you can find not just online courses but specific business English courses. One that seemed like a great option to me is on promova.com. I already have experience with this platform, and so far, I like it because it's functional, convenient, and offers good online courses for both self-study and group or tutor-led learning.
