I used to heavily stutter when I was at school. My parents didn't pay much attention to the problem but I started working on it when I entered college. It was hard to completely get rid of it, but I spared no effort in trying to minimize its effects on professional interactions.
One of the most effective strategies my speech therapist employed was training me to talk slower than average and wait for a couple of seconds before responding in a conversation. It didn't completely remedy the problem but made it less noticeable. I continue to work and improve till this day.
However, my experience with phone interviews, which is always the first stage in any recruitment process, has been nothing but negative due to this. Because they're not aware of the problem, my occasional pauses, stuttering and overall “patient” way of talking overshadow the positives. I get embarrassed when they lose interest and try to wrap up the call by interrupting me to ask another question, which makes me stutter even more.
My stuttering is a problem, I get that. But I want to show interviewers that I'm a hard worker who spared no effort in trying to get rid of this problem. I paid money, spent hundreds of hours working on it alone and with groups, and worked hard in my career to compensate for stuttering.
What's the best way to approach this? Interviewers usually reach out by email to set up a phone interview. Should I inform them of my stuttering problem so it doesn't come as a surprise?
I work in the marketing industry. My job usually requires 70% writing and 30% interaction with colleagues and clients.
