I think we all have been prejudiced at one point or another for our hearing loss/deafness. It's part of life. One important aspect in starting a career is knowledge of what works and what doesn't work.
I'm in the writing field not only because I love writing (one of my top passions), but it also is a field that doesn't require oral communication and hearing for success. It doesn't require much accommodation. I've communicated with hearing co-workers and supervisors just fine through e-mail, text, and instant message. I don't mind doing data entry either as I have strong computer proficiency and fast typing skills.
I've met several deaf/hard of hearing persons who have discovered careers in which they have used the situation to their advantage. For instance photography and graphic design--those persons have had amazing amounts of creativity through visual mediums. One deaf friend of mine excelled in woodwork (i.e., building wood furniture, bird houses, et cetera). Another deaf friend has a thing for construction and remodeling (i.e., installing carpet, tiles, painting, roofing) and his hearing co-workers have learned how to gesture with him.
