One employee at my work (I will not name it) was initially passed over for a job because he called the company by the wrong name in his cover letter. He emailed and asked what he could do better for his next job interview. That email got him the job.

He was fired some time later for messing up too much on the job. [I couldn't imagine that there would be any kind of predictor for that] ... I suppose it just depends on who you ask and when you ask them.
