Top 58 Service Desk Interview Questions and Answers for 2025

1. What is a Service Desk?

A Service Desk is a centralized point of contact between users and IT service providers. It helps in managing incidents and service requests, providing support to users, and facilitating communication. The main goal of a Service Desk is to ensure the smooth functioning of IT services and improve user satisfaction by resolving issues efficiently.

2. What are the main functions of a Service Desk?

• Incident Management: Handling and resolving user issues as quickly as possible.
• Service Request Management: Managing requests for new services or changes to existing services.
• Problem Management: Identifying and addressing the root causes of recurring incidents.
• Change Management: Facilitating changes to IT infrastructure with minimal disruption to services.

These functions help maintain service quality and improve user experience.

3. What is incident management?

Incident management is the process of restoring normal service operation as quickly as possible after an incident occurs while minimizing impact on the business. This includes logging incidents, categorizing them, prioritizing based on impact and urgency, and resolving them through known solutions or escalation if necessary.

4. How do you prioritize tickets in a Service Desk?

Tickets in a Service Desk are prioritized based on two main criteria: impact and urgency. Impact refers to the effect of the incident on business operations, while urgency indicates how quickly the incident needs to be resolved. A common prioritization matrix is used to categorize tickets into levels such as critical, high, medium, and low.

5. What is a Service Level Agreement (SLA)?

A Service Level Agreement (SLA) is a contract between a Service Desk and its customers that defines the expected level of service. It includes specific metrics such as response times, resolution times, and availability of service. SLAs help set clear expectations and ensure accountability from both parties.

6. What tools are commonly used in Service Desk operations?

• Ticketing Systems: Tools like Jira, ServiceNow, or Zendesk that help log and track incidents.

It is essential to listen actively to their concerns, show empathy, and reassure them that their issue will be addressed. Remaining calm and professional while providing clear and concise information can help de-escalate the situation and build trust.

8. What is the difference between an incident and a problem?

An incident is an unplanned interruption to a service or a reduction in the quality of a service. In contrast, a problem is the underlying cause of one or more incidents. Incident management focuses on resolving incidents quickly, while problem management aims to identify and eliminate the root causes to prevent future incidents.

9. What is a knowledge base in a Service Desk context?

A knowledge base is a centralized repository of information that contains solutions to common problems, troubleshooting tips, and best practices. It helps Service Desk agents resolve issues more efficiently and provides users with self-service options to find answers to their questions without needing to contact support.

10. Can you explain what ticket escalation means?

Ticket escalation is the process of transferring an unresolved incident to a higher level of support or management. This typically occurs when the initial support agent lacks the expertise or authority to resolve the issue, or when the incident requires more immediate attention due to its severity. Escalation ensures that critical issues are addressed promptly.

11. Describe the importance of documentation in Service Desk operations.

• Knowledge Sharing: Proper documentation allows team members to share information and solutions.
• Consistency: Documentation helps maintain consistency in processes and responses.
