Do these two paragraphs make sense? 1. The only mistake I have made so far is that I have made no mistake(or no mistakes?) even a single time.

One day he was saying on the phone, "I'm no grandstanding, but I do have gotten offered from a few of the companies in this field. We may have met before - unless you had tried out in a different field."
