When will I Receive this

<p>Sorry. In my previous post I didn't explain things well. About a week and a half ago I got an internship and we've been emailing back and forth because I had some questions. They were able to answer me. Now my last question was what is the next step for me and they mentioned this.... As for your first day information, offer letter, drug screen and background information you will receive that by COB this week? I know that COB means close of business so does that mean that they will send it by Friday or that day that I received the email which was a Wednesday?</p>
