And when you recruiters go to LinkedIn and you aren’t there, or if your profile is missing a picture or isn’t complete,
the conclusion they draw is clear: you are not a serious job seeker. Remember, the recruiter has hundreds of applicants to consider, many of whom are chancers. For them, step one day one is to throw out all those resumes that don't look the part, look dodgy or plain. You should make every effort imaginable to distinguish yourself from them and present yourself as the professional that you know you are.
