Did he get a daypass to spend time in the presence of God with the other angels during the Job incident?
An interesting question (more importantly, one I can answer without having to dig through hundreds of pages of scripture). If you read the intro to the Job passage in its fullness, see for yourself based on Satan's response to God's question.
6 One day the angels came to present themselves before the LORD, and Satan also came with them. 7 The LORD said to Satan, "Where have you come from?"
Satan answered the LORD, "From roaming through the earth and going back and forth in it."
So from Satan's response, we see that he was already roaming through the earth. In that sense, one could argue one of two things. First, it was his responsibility to roam the earth in that manner and thus he was still doing his job (i.e. not thrown out yet). Second, one could argue that he had already been thrown down to earth and thusly was going around the earth trying to find ways to attack God's people. This is the interpretation I would hold, simply based on the conversation they're having.
In the Job text, Satan is clearly presented as an adversary of God. Further, look at God's question.
"Where have you come from?"
This clearly demonstrates that Satan is not living within the will of God. Now God, by assumption (which we can leave out of discussion), knows everything, so one might ask, why is God questioning Satan if He knows everything? One sees the same thing at Adam and Eve after the fall of man (Gen 3:9 and Gen 3:13), and again after Cain kills his brother (Gen 4:9), elsewhere too, but these two references should be enough to prove my point. God questions people in the OT almost as a form of rebuke. The specific meaning of God's questions and so forth is a huge discussion (and, I might add, totally fascinating), and one I will truncate. However, I think it's very reasonable to say that, where you find God asking a question in the OT, it is almost like a form of rebuke. It's like God questions you about things that you've done wrong or after you've done something wrong.
This is my elongated way of saying, the question in and of itself demonstrates that Satan is already living outside the will of God, which means he is already in rebellion.
According to this analysis, it is clear that Satan has rebelled against God. Would God then yet leave him in heaven? Heaven is a place where God's will is *always* done (e.g., let thy will be done on earth as it is in heaven). So therefore it is reasonable to say that if Satan is already in rebellion, he cannot be allowed to stay in heaven. In this way, one can demonstrate that Satan clearly must have been thrown out already.
Nevertheless, your question is still an interesting one. Why is Satan with the other angels when they are presented before the Lord? This question is not explicitly answered. One could equally ask, why did God call for all the angels to be presented before Him? To be honest, I don't know. But for the sake of whether or not Satan is already thrown out of heaven, the question is ... relatively irrelevant, if you know what I mean. You can demonstrate that Satan had to have been thrown out already by analyzing the discourse between Satan and God.
