You can expect a structured progression that begins with a recruiter screen, followed by technical interviews with hiring managers and senior team members. The pace is generally efficient, reflecting the urgent nature of the projects you will support.

This timeline illustrates the progression from initial qualification to final technical assessment. Use this structure to pace your study; focus on high-level architecture during early rounds and deep-dive technical configurations as you move toward the final stages.

System Stability and Security

Maintaining system uptime while adhering to strict security standards is non-negotiable at Sentar.

Be ready to go over:

• Patching and maintenance cycles – How you manage updates without disrupting mission-critical services.
