i had a high failure rate in interviews...cant compare with non-stutters. but i got some very good job offers over several years (i am 40+). i am in tech field, and good at it. i wished to be in management, but i guess my personality is shaped differently, party due to childhood stammer and shyness i believe. i have been fairly successful as a tech person. I miss the feel of fast growth and authority that comes with management roles, otherwise i have had decent jobs and good colleagues.
