Hey guys, quick question. I've already signed my TAP offer letter & started the onboarding process but just received an e-mail from Accenture to come down to office for a physical interview?

Could someone shed a light on what the interview might be? Is it like a project interview (?) or could be something else? Honestly, the way the e-mail was phrased made it sound like I was still in the interview hiring process so it was really confusing....

I've already e-mailed the recruited to ask but I thought perhaps I could get some opinions here as well if anyone has experienced the same thing!
