If you look at the Service Books (e.g., Hapgood's) you will see that before the ceremony of Chrismation begins the person being received by Chrismation makes a complete confession of all his sins "from his youth up."
No Absolution is given at this point.
Later, after the formal renunciation of previos theological errors and the recital of the Creed, the Prayer of Absolution is pronounced over the person. After the Absolution the Chrismation commences.
Btw, there is a note which ends this Service: " There are several differences in this Office, as celebrated in the Greek Church; but they are not important."
I have a question about this. I was recently received from the RCC into Orthodoxy by chrismation. Leading up to it, I asked a few times if I would need to be confessed, but was told I did not. So, should the Prayer of Absolution have worked even though I was not confessed?
(yes, I will ask my priest but I am still posting the question here)
