I am filling out a job application that asks "If not currently employed, explain why" I was terminated but would rather explain why face to face in the interview. What should I write as the answer? I was thinking something like, Willing to discuss when we meet. What do you think? Thank you

A lot of things to consider. First I would write down why I was terminated on a separate sheet of paper. Then I would start editing - if it is long and involved -to get to the shortest possible answer. Sometimes in a verbal interview too much detail, considering the subject, will not make a good impression. Adopting the attitude of we agreed to diagree and here I am, is the best of a bad situation. Good luck
