The bidding process is exactly that - a process. It may take a little while before you are chosen to work your first Op. If you are having trouble getting chosen, it may be because you do not yet have a rating or do not have the skills required to complete that Op. Bidding on Ops with lower pay or longer hours, in the beginning, can help build your profile and credentials.
If you're a new Veryable Operator, you have the option of taking the Operator Onboarding Quiz to gain your first rating. Interested? Check out more details in this article.
