Unable to secure any job offers due to my stutter

Unable to secure any job offers due to my stutter I (28F) have a situational stutter meaning you wont find me stutter in normal occasions but when I am giving interviews, I really get stressed and I get stuck on words. I had 5th interview today, where the interviewer thought that I am shy and she indirectly said that the role isn’t for shy people. I have to much to say but I feel this habit of mine is stopping me from achieving things. I have worked in Accenture and now I have come to Germany to do my masters but every interviewer expects me to speak perfectly. I know it isn’t wrong at their part, but I feel highly demotivated and feel that my capabilities go unnoticed somehow. Any tips on how to combat this would be greatly appreciated.
