Trending @Accenture; Regarding project calls and project for freshers

Yesterday, I got a project call and I gave the technical interview. Today in the morning they sent me a message in teams like you are selected . Kindly wait for hard lock mail .

Should I wait for that mail for few days or attend more calls ?

And one more doubt if they say I will get mail soon . Will I get or there are any chances of not sending the mail even i get selected ?
