How many law students are actually like this? Medical school has "gunners" I'm sure that law does too. But on average do most people treat each other with respect or is there a constant competitive rat race to get ahead at all cost?
There is nothing you can do about this, so it's completely unproductive to overthink it. And firms don't waste their time interviewing people they have no interest in hiring. I guarantee you that the firms did not put as much thought into the order as you are.
