I filled in the application to join the talent network - it said sending a CV was optional do I didn't and it hasn't asked me to.
I had an email but not inviting me to do any particular work. Basically a welcome and 'view all jobs'. There were some transcriber ones there but they wanted Australian/New Zealand English speakers. Saw the Web Search Evaluator roles on another page.
Guess it's a case of sitting to wait and hear now?
The deadline for this project is 11pm tommorow (22/7), local UK time. In addition, people who complete the task today and with high quality may be invited to further rounds, or to further opportunities being paid to recruit others to the task.
