Deloitte PHT Mail received after Rejection on portal

Hi All,

I had been rejected for the consultant role at Deloitte USI on 8th of August and almost after 1 month I got PHT mail on 12th sept saying that "we are delighted to inform you that we would like to take your candidature ahead."

Should I hope for the OL or it is some glitch ?

Have anyone face this?

Please clear,
