How to hire the best system administrator using an online Bash test


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 do system administrators do? A system administrator’s job description

The specific tasks a system administrator is responsible for vary depending on the organization and its needs, which are usually based on its size and the systems it uses.

what system administrators do

The following are some of the key responsibilities of system administrators: 

  • Design, manage, maintain, and optimize the company’s computer systems, including software and hardware

  • Manage networks and make sure they’re secure and functional; set up and configure LAN and WAN networks 

  • Set up, configure, and maintain Linux or Windows servers and virtual machines

  • Troubleshoot network, system, and computer failures or problems

  • Manage user accounts, groups, and permission levels

  • Maintain the security of all systems and ensure the company’s IT infrastructure is not exposed to security risks

  • Design and implement backup and recovery procedures 

  • Maintain uninterrupted network connectivity and availability (including internet connection and email servers)

  • Monitor systems’ performance and availability to maintain continuous uptime and address issues as quickly as possible

  • Offer technical support and training to employees to make sure users have the knowledge needed to not expose the organization’s systems and data to security breaches 

In short, system administrators are responsible for the smooth operation of a company’s networks and IT systems and help ensure that all employees can access the systems they need.

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. 

If your company is using Windows for its servers and IT infrastructure, then sufficient experience in Windows server administration and knowledge of Microsoft 365 are indispensable. 

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:

Hire system administrator using bash test
  1. Prepare a job description: First, write a comprehensive job description. Include the responsibilities of the role, must-have skills, and nice-to-have skills. 

  2. Write a job ad: Based on the job description, write a job ad. Don’t forget to mention the role’s location and the perks and benefits your organization offers.

  3. Publish the ad on relevant job boards and start receiving applications: Once your job ad is ready, you can publish it on your website, LinkedIn, and relevant job boards. Make sure the application process is simple and straightforward.

  4. Create a skills assessment: Create a skills assessment of up to five skills tests, which you’ll use to evaluate applicants and determine who’s fit for the job. Assess must-have technical skills (such as Bash knowledge) and non-technical skills (such as communication abilities).

  5. Administer skills tests to all applicants: Invite all applicants to take your skills assessment. Provide candidates with enough information about your hiring process to maintain candidate engagement and ensure a positive candidate experience

  6. Evaluate and analyze applicants’ performance: Check the results of the skills tests to see who your best applicants are. Compare results and filter out candidates who don’t have the right skills.

  7. Invite the best applicants to an interview: Invite the top-performing candidates to interview for the role. Again, make sure you provide enough information on the next steps of the hiring process to maintain a good candidate experience.

  8. Conduct interviews: Conduct structured interviews to minimize bias and evaluate applicants accurately. Ask interview questions adapted to the role’s seniority level and the systems your organization is using.

  9. Speak to previous employers: If necessary, speak to your top applicants’ previous employers to ensure they have what it takes to be successful. Always inform your candidates about this. Perhaps this goes without saying, but don’t call your applicants’ current employers without discussing it with them first. 

  10. Make a hiring decision and extend an offer to the best applicant: By this point, you’ll have all the info you need, so make a hiring decision and send an offer to the best candidate. Discuss the contract’s terms and start date.
