Say goodbye to the rest of your life as an attorney, the chances of you getting a job are 0%. Recruiters spend an average of two hours on each resume, checking every single comma and period, along with the tenses of every single bullet point. You are screwed!
I would send an updated resume with the problem fixed, along with a detailed letter explaining how you made the mistake, and what you have learned from the experience, citing primary authority if necessary. Be sure to include at least three references who are willing to back up your reasoning on how this erron was made.
Also, send an email to every partner in each of the firms informing them that you made an erron on your resume. This won't increase your chances of getting the job, but it will show them that you care.
