The reports vary, just as they do with any MSC. They have phone shops that require a lot of narrative, but are relatively simple.
There are some shops that-- not unlike most shops of this ilk-- are really hard (detail oriented, time consuming, investment of energy). The only thing I can tell you that might "help" you in deciding which shop they are is that these are shops that are often left on the board come the end of the month. I recommend _not_ taking them until you can ask for a bonus (they're not worth it, IMHO, without). Other than that, trial and error will help in the determination.
Beyond Hello has some of the nicest schedulers/reviewers that in the biz. They pay on time, they have steady work (even in rural areas, it seems), and their shops can be fun (even the tough ones!).
