It's entirely dependent on the firm. There are a couple structures that are quite common, and if I had to guess the 10/15/20% bonus structure is the most common on the street overall, but you really can't know without talking to associates at the firms. Some have a flat bonus for all associates. Some do flat bonuses for all that hit a certain billable target. Some do increasing bonuses based on billables, while others do increasing bonuses based on partner discretion.
You wanna call other students broken, then sure. Maybe they are. Maybe they're sore losers, and maybe they simply can't own up to the fact that they played the game wrong.
But guess what, fairly or not, a lot of your classmates and a lot of lawyers are still gunna think you're an ass. If you're fine with that, then be my guest and post away lmao
