If the interview went good, then you're most likely a covert stutterer (I presume the interviewers only realized that you stutter after you told them so). I'd say use that to your advantage, take the job, and use the job to practice speaking. Think of it this way, you were never going to take this job anyways, so you might as well take it knowing that you can always walk away. Another thing that most people (like me) in their 40s realize is that stuttering is not the end of the world. If you're able to express yourself, with or without stutter, 'thats' what really matters. So, here's the kicker: LET YOURSELF STUTTER. Usually this frees you up from the pressure of appearing to be fluent, and consequently, you'll be at ease, and likely stutter much less. Use this job to build this type of carefree attitude, which trust me, is the best thing you can do to drastically improve the quality of your life .............. (or wait until you reach your 40s and 50s, get frustrated of being afraid of stuttering all the time, and THEN start giving two shits about your stutter, your choice).....
