Most firefighter candidates don’t fail the background investigation because of one major issue.
They fail because of patterns.
Things they didn’t think mattered.
Things they didn’t explain correctly.
Things that raise concerns about judgment, honesty, or reliability.
And once those concerns show up, departments move on.
