I have not actually heard the phrase "consensus meeting." It probably means "a meeting in which the decision is made by consensus, not by vote." "Consensus" is almost, but not quite, unanimity. In many kinds of formal meetings, people take sides, eventually there is vote, and a decision is made based on the vote. "The majority rules." If seven people support X and five people are against X, then the decision is X. The decision represents a majority of the members. The decision does not represent the committee as a whole. Five people are unhappy. "Unanimity" means that there was a vote and that everybody voted the same way. "Consensus" means that the discussion will continue, maybe for a long time. It continues until the meeting chair thinks there is an answer that represents the meeting as a whole. It is not "unanimity" because no vote is taken. When it is over, some people may not fully agree with the decision. However, everyone agrees that "this is what we decided." Chair: "OK, the sense of the meeting is that we need to put a new roof on building B. Wait, John, do you have a comment?" John: "I still think we should be re-roofing building C at the same time. But well, OK, yes. I can go along with this decision. We can get started on re-roofing building B." Chair: "Good, I think we have consensus. The meeting is adjourned."

In a consensus meeting a decision is made when all members of the group come to the same decision. When it comes to consensus decisions the group has to find a solution that everyone can agree on. So in this case there are consensus meetings held when looking for managerial and executive level talent. Therefore they would not simply take a vote and go with the majority, but find a decision that everyone agrees on, or can deal with.
