Tell us about a mistake you made in any of your affiliate marketing assignments.
More than the mistake you made, the interviewer is interested in finding out how you overcame the mistake. Did you learn anything from the mistake?
While answering this question you need to tell the interviewer about the mistake you made, why did this mistake occur and how were you able to rectify the mistake. You should let the interviewer know how this mistake helped you in increasing the return on investment or how did you build a better relationship with the affiliate.
