I also struggled to get a job in finance. I had some social benefits that made me able to look for a job and get the benefits for a period of 2 years max. I finally got a job on my last month of benefits. I changed attitude and my stutter stopped in the interviews. Try do to the same. If you feel that “THIS” interview is a must to ace to get a job, you will always pressure yourself. See it as a journey, part of life experiences and “enjoy it” and you will feel better and stop stuttering at interviews. I know it sounds easier than it is and indeed it is hard at first.
