Database Administration & Maintenance

You must demonstrate mastery over database lifecycles. This includes performance tuning, replication, and disaster recovery.

Be ready to go over:

• Performance Tuning – Strategies for optimizing queries and indices in high-load environments.
• Replication & High Availability – How to maintain data integrity across different geographical sites.
• Backup & Recovery – Designing plans that meet strict Recovery Time Objectives (RTO).

Example scenarios:

• "Describe a time you had to recover a corrupted database while minimizing downtime."
• "How do you handle schema changes in a 24/7 production environment?"

Unix & Infrastructure Operations

Since the environment is heavily reliant on Unix, you must be comfortable at the command line and understand kernel-level interactions.

Be ready to go over:

• Resource Management – Monitoring CPU, memory, and disk usage to prevent system exhaustion.
• Automation – Using scripting to reduce human error in repetitive tasks.
• Security Hardening – Applying patches and securing system access points.

Example scenarios:

• "How do you identify a process that is causing a system-wide latency spike?"
• "Explain the steps you take to harden a Unix server against unauthorized access."

As a Systems Engineer, your day-to-day work centers on the stability and efficiency of critical infrastructure. You will spend a significant portion of your time monitoring system health, responding to incidents, and executing planned maintenance.

Collaboration is essential; you will work closely with developers to optimize database queries and with network teams to ensure low-latency connectivity. You will also participate in capacity planning, ensuring that the infrastructure can scale ahead of business growth. Your primary deliverables include stable production environments, automated maintenance scripts, and detailed documentation for complex system configurations.
