Commentator
As a commentator, you are responsible for entertaining the live stream during the game and any pauses in-between. You should comment on all the gameplay that is happening using the correct terminology and a high level of English. You won't be doing this job alone, so it is important that you don't interrupt while the other commentator is speaking and it is also preferable if you don't mind being camera shy.
Anything can happen during the game, so be sure you can keep the flow of the stream entertaining and that you have some kind of good chemistry with your co-star. It is important that you have very good terminology and understanding of tactics and that you can almost predict what is going to happen (e.g., “I think team A will eco here, it would be in their best interest”). You will be in a separate voice channel with the streamer, who will be screen-sharing the game to both you and your co-commentator, and after the game we would like you to interview a player from the winning and losing team so it is important to think of questions (we will have some generic questions which you can ask if you can't think of anything specific to the player).
