Pros
Prompt payment for the work completed. Some interesting research papers.
Cons
Heavy micro-management and feedback. The company has idiosyncratic grammar and word choice rules you are expected to memorise that have nothing to do with standard modern English grammar, but their 'house style'. You are paid by the hour not the word count involved. Consequently, as an editor you may spend a long time deciphering the terrible English and almost rewriting a document to have a senior editor come along and accuse you of 'bad English' as the final product does not adhere to their eccentric rules. The hourly pay rate sounds good at first, but to earn that rate you would have to work like a plug and play device that was able to download and operate their peculiar in-house grammar and word choice system. I was hired as a feeelancer, told I'd passed probabtion, then discarded when their surge period ended. Lots of staff/mamangement cliqueyness and politics at play in the background. Would not recommend. Avoid if possible.
