1. What is the role of an application support analyst?
An application support analyst provides technical support for business applications, manages incidents, investigates errors, and ensures software systems function as intended.
2. How do you handle high-severity incidents?
Follow the defined escalation path, inform stakeholders, initiate impact analysis, log the incident in a tracking system, and coordinate with teams for resolution while maintaining updates.
3. What is the difference between L1, L2, and L3 support?
- L1: Basic troubleshooting, password resets, user queries
- L2: Technical investigation, log analysis, configuration issues
- L3: Code-level debugging, handled by developers
4. What tools have you used for monitoring or logging?
Common tools include Splunk, ELK Stack, Nagios, Zabbix, AppDynamics, New Relic, and Grafana.
5. What is a service-level agreement (SLA)?
An SLA defines the expected level of service and response/resolution times for incidents or requests.
6. How do you prioritize tickets?
Based on severity and impact:
- P1: System down
- P2: Partial impact
- P3/P4: Minor or cosmetic issues
7. How do you analyze application logs?
Use tools like Splunk or command-line tools (e.g., grep, tail) to search for error patterns, exceptions, or performance bottlenecks.
8. Can you explain incident vs. problem vs. change management?
- Incident: Unexpected issue requiring immediate fix
- Problem: Root cause of recurring incidents
- Change: A planned update or fix to improve systems
9. What is SaaS in interview questions?
SaaS (Software as a Service) is a cloud-based model where software is accessed over the internet. Support involves handling access, configurations, integrations, and performance.
10. What are some main defects you may encounter in application support?
- Memory leaks
- Connection timeouts
- UI glitches
- Data sync failures
- API failures
- Configuration mismatches
11. How do you handle user complaints about performance issues?
Monitor CPU/memory, check logs for errors, use profiling tools, simulate load if needed, and escalate if a fix requires code changes.
12. What is root cause analysis (RCA)?
RCA identifies the underlying reason for an issue. It often involves the “5 Whys” method, log analysis, and reviewing system dependencies.
13. What is batch job monitoring?
Monitoring scheduled tasks for completion, failures, delays, or incorrect results. Tools: Autosys, Control-M, or cron logs.
14. What are common scripting skills required?
Bash, Python, or PowerShell are often used to automate checks, monitor logs, or manipulate data.
15. What is your experience with SQL?
SQL is essential for querying databases to validate data, check issues, and debug transactions or backend processes.
16. What is version control and why is it important?
Version control (e.g., Git) helps track changes, manage deployments, and collaborate effectively with development teams.
17. What is DevOps and how is it related to application support?
DevOps combines development and operations. Application support often works alongside DevOps to ensure CI/CD processes, monitoring, and incident handling.
18. How do you communicate with non-technical stakeholders?
By simplifying technical terms, focusing on impact and resolution, and maintaining clear, timely updates.
19. How do you document incidents or procedures?
Use ticketing tools like Jira, ServiceNow, or Confluence for documentation, including RCA, steps taken, and preventive actions.
20. How do you manage shift handovers?
Maintain handover notes, update logs, communicate pending issues, and brief the incoming team on priority tasks.
21. What metrics do you track for application health?
Uptime, latency, error rates, resource usage, and transaction success rate.
22. How do you support both on-prem and cloud-based applications?
Use hybrid monitoring tools, understand network and infrastructure differences, and manage access/security accordingly.
23. What is a change request and how do you handle it?
A documented proposal for a change. Review impact, test in lower environments, and follow approval workflows before deploying.
24. How do you ensure compliance and security?
Implement access controls, audit logs, encryption, regular patching, and adhere to compliance frameworks like ISO, SOC2, etc.
25. Have you worked with ticketing systems? Which ones?
Yes. Common systems include Jira, ServiceNow, Remedy, Zendesk, and Freshservice.
