But having found permanent employment on there, and also having hired people on there, sorry to be biased, but if you sound like a native speaker and can hold your own in a Zoom meeting, that's half the yardstick met for me when it comes to hiring.
The number of foreign devs whose English is so bad that you just have to communicate in writing is high. Business people like to communicate verbally, so if you aren't confident, practice.
Hmm, I wonder if there is a startup out there that does English training to help non-native English speakers sound like native speakers? My wife's first language is German, but she really put time into becoming a native-level English speaker, so it is possible.
