What if your last employer discriminated against you?
“An interview is a place to focus on the future and the new job. So if you don’t want to hurt your chances, you can use the techniques suggested in the “explaining why you were fired” article anyway [link above], and don’t blame a prior employer, even if they were in the wrong.
Find the most positive reasons and focus on YOU and your strengths as they match the needs of the new job. Look at whatever reason was used when you were fired (even if the underlying reason was different), and build your answer based on that, focusing on how you’ve overcome / learned / improved / moved on for better or whatever paints the most positive picture of how you handle obstacles and move on toward the future.
As for the discrimination itself, if you truly feel you were treated unjustly and want to hold your prior employer responsible, you can look into filing a lawsuit [separating this from your interviews]. No one should get away with discrimination. Just be very sure that you want to do this and have ample evidence, since you are starting something that may go on for a long time and may even affect your new job: EEOC ~ Filing a Lawsuit
But remember … what often serves you best [no matter who done who wrong] is to get yourself to a new job where you are appreciated and get “revenge” by being a star. So do what you need to do, and then leave the past where it belongs to make room for new beginnings.”
