System administrators play a vital role in maintaining your organization’s IT infrastructure and ensuring it’s secure, up to date, and functioning efficiently.
If one of your IT systems fails, the consequences can be disastrous for your business. And the longer it takes you to get it back online, the higher the risk to your performance, profitability, and reputation.
For this reason, finding and hiring the best system administrator for your company is critical. To do it successfully, you need to be able to evaluate their skills and expertise accurately and without bias.
One of the best ways to evaluate the skills of your future system administrator is to use skills tests early on in the recruitment process. Pre-employment tests such as the online Bash test enable you to quickly identify top candidates and disqualify those who don’t have the right qualifications.
In this article, we’ll discuss the role of a system administrator, the skills they need, and how you can easily hire the right sysadmin with the help of skills testing.

What skills do system administrators need to be successful?
In this section, we’ll briefly discuss the skills that system administrators require to manage and protect the organization’s IT infrastructure successfully. Again, the specific skills needed will vary from role to role and business to business, but there are some high-level abilities that most system administrators should have.
You can use the skills listed in this section to prepare a skills assessment to give to candidates during recruitment.
With TestGorilla, you can combine up to five skills tests in a single assessment and administer them to applicants all at once. This gives you a detailed overview of your applicants’ skills and enables you to easily shortlist the best candidates and invite them to an interview.
1. Problem-solving skills
An important part of a system administrator’s role is solving problems and troubleshooting different types of malfunctions. This makes problem-solving an essential skill for practically all system administrators, regardless of their seniority level and the specific systems they work with.
2. Knowledge of Windows or Linux administration (or both)
Depending on the systems your business is using, your sysadmins need relevant knowledge of Windows or Linux administration – or possibly both if your organization has complex infrastructure.
On the other hand, if you’re using Linux servers, then Linux administration skills and knowledge of the Bash shell are key. TestGorilla’s online Bash test can help you identify applicants who are familiar with the Bash shell in Linux and can use it confidently to improve your company’s efficiency.
The line between Linux and Windows is starting to blur in most organizations, so both Windows and Linux system administrators are likely to have practical experience with both operating systems.
3. Security and monitoring expertise
Securing all business data and systems is a major part of a sysadmin’s job. To achieve this, they must have the right security skills and knowledge of the best practices in user permission management, risk assessment and management, and monitoring.
Additionally, they need to stay informed on the latest security trends so that they can protect the company against major threats.
4. Communication skills
System administrators have to communicate with many teams and stakeholders and make sure everyone is on the same page regarding the company’s needs in terms of IT systems, software, and hardware. They also need to support employees by addressing specific technical issues quickly and efficiently.
Therefore, having the right communication skills is essential for sysadmins.
Other technical skills
Depending on the systems and software tools the business uses, sysadmins might require other relevant technical skills to be successful. For example, they might need to have sufficient knowledge of the following:
