It can, especially if the communication between you and your recruiter is not clear and often. Each of you should be sharing information with the other on a regular basis. If the recruiter's goal is to find you a job, there shouldn't be a problem. I'm a self-taught programmer in several languages. I have nearly 20 years of sales and marketing experience with traditional and start-up firms.
Any advice is appreciated.
Some even specialize more in sales or more in marketing. If you have learned languages, but not used them commercially, that should be indicated. What's the best way to find someone with that or any other specialty programming talent. Many of them also require CGI and Java is a plus. What I lack is any kind of paper backup for my knowledge.
