General skills to build for IT job roles

Beyond having technical skills, such as programming, IT professionals and employers look for workplace skills like communication, since technical skills are learnable through hands-on work. Having a balanced set of both types of skills can make you an attractive applicant for IT roles. Here are some technical and workplace skills to consider building as you prepare for a career in IT. 

Technical skills

• Computer literacy: As an IT professional, you’ll spend a lot of time using computers, so understanding how to operate them and their basic functions is necessary.

• Coding: Many IT roles require coding knowledge in various programming languages, depending on your specific role. You may help code or develop new software and applications for your company.

• Application development: Having experience with application development can help you understand the back-end of the software you’re using. You may find this helpful in creating new software or applications and monitoring computer systems. 

Workplace skills

• Analytical: Analytical skills like critical thinking can help you identify and solve technology-related issues. For example, you may need to assess the status and identify computer system and application errors.

• Communication: You’ll communicate with various teams within your organization as an IT professional. This includes explaining technical concepts in a way that others can understand. 

• Organization: In an IT role, you’ll be tasked with multiple duties or projects at once, making organization a critical skill for success. With proper organization, your efficiency and productivity at work will drastically increase. 

• Problem-solving: Troubleshooting problems with the technology systems in your company can be difficult and confusing, so having advanced problem-solving techniques can lead you to be an effective team member. 

• Time management: IT professionals often have time-sensitive tasks with hard deadlines. It’s crucial to prioritize your time, delegate tasks when needed, and complete projects correctly by their deadlines. 

How do I list IT skills on a resume?

You can list your IT skills in a separate “Skills” or “IT skills” section, and make sure you’re specific; for example, instead of listing your skills as “programming languages,” list them as “Python, Java, C++.” Include your technical skills first, starting with your greatest proficiencies or skills listed in the job description, and then provide your soft skills. If you think your skills require more context, detail, or examples, you can also describe them in the “Work experience” section. 

IT education requirements

Many IT jobs require that you have an associate or bachelor's degree. You can attain a degree in various fields to qualify for IT roles, such as information technology, computer science, or computer engineering. Some common courses you’ll take to help prepare you for an IT career include statistics, calculus, data networking, and information security. Some employers also accept relevant experience and certifications in lieu of a college degree.

To better position yourself to reach senior-level positions, you can choose to pursue a master’s degree in any relevant field of study. While hands-on experience in the IT field will help you to become an attractive candidate for higher-level IT roles, an advanced degree can be an essential asset to prove your expertise and dedication to your work.
