+# personality mismatch under pressure
+
+*(common gotcha)*
+
+## what happened
+
+teamed up with someone who seemed fine in casual conversation, but under sleep deprivation and deadline pressure, they became impossible to work with — argumentative, dismissive, or checked out entirely.
+
+## why it's a gotcha
+
+hackathons are stress tests for group dynamics. people behave differently when they're tired, frustrated, and running out of time. someone who's great at a meetup might be terrible at 4am when the API is down.
+
+## the fix
+
+if you can, team with people you've worked with under pressure before. if you're teaming with strangers, pay attention to how they handle the first setback. that's who they'll be for the rest of the event.
