2. Series of Short-Lived Jobs

If you had a series of jobs that you have held for short periods of time, it might be a good idea to take them out. You don't want your resume looking disjointed and you don't want employers to think you don't have focus.

Some exceptions can be if you worked somewhere really prestigious that would make you look like a better job candidate or if you had a long period of unemployment and had nothing else to put in your resume. Still, even in those circumstances, be very cautious about what you include.

3. Personal Information

While you do need to include a certain amount of personal information to ensure that a technology recruiter contacts you, it is unprofessional to list a current business phone number or email address on your resume. Avoid confusing the recruiter with multiple phone numbers. List either your home number or cell phone, but make sure the voice mail greeting sounds professional. Personal email addresses should be nondescript and include your first and last name.

While you may think that including links to social media sites makes you appear young and hip, your LinkedIn profile is the only SM site that should be referenced on an IT professional’s resume. Details such as your current salary and future goals are topics that should be reserved for an in-person interview.
