How hard is it to work in corporate sector as a stammer,has anyone face ...??

Not hard if you work with Toastmasters or someone to improve your stutter Understand your frustration but ensure that you do mention this as a disability when applying to large companies so that they do make arrangements during your interview Indian and other small companies don’t care but large MNCs do care

Feel for you. It's tough. Join a humane org. Might be easier if you are diversity commodity easier to overlook

If you mean the words coming out delayed or repeated while talking, it doesn't matter most of the time if you are in a good team.

Only while you present to larger audience unknown or new folks will be there, rest mostly you can get things done via mail or IM.

Stammering, the speech impairment you mean?
