I recently signed up to Appen looking for work and I applied for a search engine evaluator job from Project Yukon. While trying to access my application, I could not locate the job on my Dashboard the next day and also had trouble doing the other tasks. I was told I had a VPN but I never installed one on my computer and contacted customer support.
Today I was trying to sign into Appen after receiving an email to finish my application and was given an "Access Denied" message. Appen has not contacted me back yet in customer support. I'm disappointed that I was subjected to this as a new member, I recommend finding a job on another site.
