I am sorry to hear this. But dont attribute your interview failures to your stutter. The job market as far as i know is not good. You have already worked in a customer facing job why are you not focussing on that strength instead of focussing on your stutter. There will always be more rejections but trust me they wont be bcz of your stutter . May be they are looking for some other experience or some other expertise. Its very easy to atribute the failure to a stutter bcz thats human nature. Have patience. My strike with job interviews is just 5% 😂. But i dnt blame my stutter i have my 12 years of exp to back me. So look at your strengths. Its very easy to blame something thats not in your control. Keep giving interviews and learn from the failed ones till you strike gold.. 🙂. Best of luck brother
