Do you prefer to read other's works first, before they read yours? Or vice versa? Do you prefer to read something you would find interesting? Such as genres you read and write in? Or can you read anything? Perhaps chapter swapping? I read one, you read one, onwards and forwards? The reason I ask all this is that I'm currently working on my fifth draft of a book in my main book series, and in X months, I may take the step to ask for collaboration. However, considering that I am a very slow reader, even for work I enjoy, I would probably want to read my collaborator's work first. This would also give them an idea of my level of feedback, so they aren't disappointed. Or in worst case, they give me tons of good feedback and I can only repay the favour halfly. So, how do you prefer to collaborate with others? What steps do you take? Methods to use? Etc?
I read relatively fast, and I don't require people read my stuff in order for me to read theirs. I find genuine joy in beta reading, and have kind of made it a hobby. I ask what kind of feedback they're looking for, and if they want me to point out spelling/grammar/punctuation stuff. I don't do close line edits, though, because I feel like that's just distracting from finding the story. I don't generally have a preference for reading something, either. I don't know how much help I'd be in a specific non-fiction book, like sports history or something like that, but I like helping people with their work if I can.
