Rate your communication skills on a scale of 1 to 10. Give examples of experiences that demonstrate the rating is accurate.
You have to discuss how skilled and good you are in communication on a scale of 1-10. Try not to give yourself a 10 as nobody is perfect and we all are in a learning phase. A rating of 10 will let your interviewer know that you are overconfident and there is no space for any improvement or feedback. Alternately also avoid giving you too little and try to be in a range of 7.5-9 followed by an example to prove it.
E.g. I was engaged in a remote team of developers and wanted to report a bug. I have sent an email and described the bug thoroughly but developers were not able to reproduce that. Instead of wasting time I have recorded my screen, narrated the video, and shown them stepwise what I have observed and they have accepted that bug.
