Thank you for taking the time to answer. I just wanted to make it clear that I don't always get negative feedback but when I do, it makes me very stressed and I can not think straight after that. Someone also mentioned in this thread that being a non-native speaker is hard, which is true in my case.

I have worked with mid sized companies so far, where I have managed to work with it but I will start a FAANG job soon and just don't want to be in this situation when I start, specially when I am going to meet 10x more experienced and sharp engineers.
