I'm applying for nile and inari on appen and for both I have to fill out a part saying company currently working as SEE. Can you only be recruited for these projects if your currently working as an evaluator?
No, they are hiring for those roles as standalones at the moment. But,
If you haven't worked for Appen or Lionbridge before I wouldn't appy for one of those roles as a first position anyway.
Those roles last a year at the most, are 7 hours a week each only, and doing them first could stop you getting better paid, long-term jobs with those companies.
If you're a WSE virgin I would apply for Lionbridge first, they have a few roles (not the socal media one) that they are hiring for, but they will not hire you if you have worked for another company.
After that go for apply for a WSE role at Appen. You can add one of the social media jobs once you've been hired.
Probably more info than you wanted, but there you go
