Playing trios

When playing trios I find that a lot of the time my teammates are running into every fight and shooting all the A.I and by the time we are at the boss there are multiple teams already hunting us down. And know our exact position. Then we usually die, spread out and unable to revive.

My question is, is this the general playstyle of hunt or do a lot o of people play more methodical and quiet. I play solo a lot now and have adopted a more quiet and positioning playstyle which has been working quiet well. But it seems almost impossible to get that to work in trios or duos.

Any feedback?
