Accenture Content Moderator interview questions

I had the worst experience with these people and here is why: While I was working with an international company here in Ireland for almost a year, I received a job offer from Accenture Ireland, and after being selected and I signed the formal contract with them just 1 day before about to start with Accenture, I received a call from Cathal Campbell and Nikkita Tivari which they are from the "Onboarding team" and "HR team", telling me that I can’t start to work with them since I need to have my stamp 4 at least 6-month update in advance before the expiration date which is this December 2022. I had to say that they had this information (about my GNIB and Stamp 4 Visa) and all my legal personal information since they called me offering me the job and contract which it was almost 4 weeks before I was supposed to start with them! They left me without a job as they made me sign a contract the same week that I got selected for this job offer putting me under pressure to sign the contract and asking me to give and confirm my notice of the job that I had at that moment and they left me without any jobs and the worst thing of this it's that they are not even answering any of my calls or any of my emails because I know this is not legal! How come they can leave people like this when we have to pay rent and bills and we depend of a job to do this, they are irresponsible with no ethics! and this is inhuman! so please, DO NOT ACCEPT ANY JOB OFFERS FROM THIS PEOPLE!
