Considering my previous question here and one of the answer, one thing I thought I might be doing wrong is most of the times when applying online for a job, I tend to use auto generated resumes that those websites generated based on my information entered for my profile. So when I apply for job over Stackoverflow jobs I use the default resume that it generates while applying from my profile. Or using LinkedIn profile with my application instead of a resume in PDF or word.
I wanted to know that will this lower chance of my application getting through? Is it fine to use this resumes or should I go through old manually made document? Usually I check and update profile around every 2 months.
