I'm new to Upwork and still getting my bearings.
I've submitted some proposals and twice had a response asking me to sign up for a Skype interview. I'm not opposed to interviewing, but it did give me pause. I suppose I was anticipating communication being done through Upwork's platform. The clients are Upwork Plus, but payment unverified.
Does this sound fishy? Or am I being too cautious?
Under the new rules, all communication before you have a contract with a client has to be done through Upwork messenger. So, no, you should not do your interview over Skype.
As the Wes already said, please let them know that sharing contact information before a contract has started is against Upwork’s Terms of Service and that all communications prior to the contract starting must take place on Upwork. We also encourage you to let us know if a TOS violation has happened by using the “Flag as Inappropriate” option throughout the platform. You can learn more about user reporting here.
