Trending @Accenture; I got a Smart ITP Initiation mail from Accenture

I am a fresher in Accenture. I joined last year on August and completed my stream training in December . Since then I have been on bench. I didn't not get any project or interview calls since then. But today I got this mail and it states that I will get interview calls and I have to accept it. If they reject me two times then there will be a capability assessment and if I don't clear that then I will be terminated from the company. I am confused and nervous right now. People who have gotten the mail before can you please tell me how I need to proceed and what happens after this? Thanks in advance.
