I think you may be right, as it says they came to present themselves before the Lord. They wouldn't need to to do that if they had been angels. Unless God brought angels along to be a part of the discussion - which seems unlikely, in view of the fact that the term here, "Sons of God" - probably refers to humans. They are not called "Sons of God" again in Job, I see - at least - not as being present in this event. And the "Sons of God" - in this event, are not recorded as having said anything, in this early part of the story, before the tragedies happened. I don't know who these men may have been. And Job's 3 friends didn't show up until after the calamities had taken place.
Job 2:1
2:1 Again there was a day when the sons of God came to present themselves before the LORD, and Satan came also among them to present himself before the LORD.

KJV
4Where wast thou when I laid the foundations of the earth? declare, if thou hast understanding.
5Who hath laid the measures thereof, if thou knowest? or who hath stretched the line upon it?
6Whereupon are the foundations thereof fastened? or who laid the corner stone thereof;
7When the morning stars sang together, and all the sons of God shouted for joy?
