Technology is part of almost every job today. Most of us use some sort of software program to do our jobs. You might think it's implied that if you do a certain type of work that you are proficient in the required technologies. But, when it comes to job search, you should list all relevant technologies you use on your resume and LinkedIn profile.
Recruiters look for keywords and specific technologies are at the top of the list.
When a recruiter is given the job of finding several good candidates for a open position, they start the process by getting what is called a "req" - it's a list of specific hard skills that the hiring manager requires as a minimum threshold for a person to be considered for the job. Recruiters then go to tools like LinkedIn and their company's existing ATS and put these requirements in to see which candidates match. Many times, it's technology proficiencies that dominate the list. That's because hiring managers want you to hit the ground running. They don't want to waste time teaching you how to use technologies that are needed to do the job quickly and effectively.
Let's say you work in accounting or project management. Both of these fields require heavy use of MS Excel. You might think, "well of course I am great at Excel, I couldn't do my job without it." But, recruiters don't look at it that way. Their jobs are to present candidates that 100 percent match the basic requirements. Thus, if you fail to list you have MS Excel experience, you won't show up in their search results. With thousands of people competing for the same jobs as you, it's not hard to see how you might be missing out on opportunities because you failed to keyword optimize your resume and LinkedIn profile to include all the technologies you use regularly.
P.S. - Resume and LinkedIn profile designs have changed a lot in the last year.
In addition to making sure you have the right technologies listed on your job search tools, it's a good idea to take some time to review all the latest trends in resume and LinkedIn profile design. Recruiters look at thousands of candidates each month. If you want to stand out, you need to understand what gets their attention. Unfortunately, it's always changing. Smart job seekers realize putting extra time into getting their tools current are the ones that get more recruiters contacting them for positions.
