請告訴我 「即便退一百步來說」 的英語！

・For argument's sake, let's assume that

例句
Since my friend was worried about whether he would receive a job interview or not, I would like to say, "For argument's sake, let's assume that you fail. However, even so, that will become a good experience."
我的朋友正在煩惱要不要去面試，所以我想說：「即便退一百步來說也沒有成功，這也會是一次很好的經驗」。

這句英語是在說：「為了討論方便，我們假設～」。
"for argument sake"也可以用"for the sake of argument"。
"let's assume that ~” 即使是用"I'll grant you that~"或"I'll concede that~"也是可以的。
