"Nevermind, I don't work with people who use idiotic interview processes. I can only imagine how dysfunctional and adversarial your company is, based on this idiocy".
Thank you so much for your time and consideration, but due to unforeseen circumstances beyond my control I must regretfully withdraw my application at this time and apologize for any inconvenience it may cause. In the future, if a similar role should become available, please feel free to reach out to me. Thank you and have a lovely rest of the week.
