Lack of Focus
The first step in a successful job search begins with identifying your goals. Clarify specifically what you want in your next job or career including your next job title. I've heard countless job seekers say, "I'll take anything" or "I'm open," when asked what kind of job they're seeking. The candidate who'll take anything, ends up with nothing。
Look at your resume. What is your objective? Avoid either failing to state your objective or listing several objectives. Either extreme can work against you as you'll appear unfocused, uncommitted or unqualified. While many of us wear many hats throughout our careers, it's best to focus on only one hat, or specific job title, for the resume. Employers today tend to look more for talented players who understand and specialize in a niche rather than those who are more general in nature。
So ask the questions, "What's my niche, specialty?" "What special problem do I solve?" This might be one specific job title. If so, then highlight that and drop the laundry list of "qualifications."
