To succeed in the Sra Group interview process, you must prepare to demonstrate both technical depth and a strong understanding of the defense and federal IT landscapes. Your preparation should focus on showing that you can deliver reliable software within highly structured, regulated, and secure environments.

Technical & Domain Mastery – You must be ready to speak in detail about your primary development languages (such as Java) or specialized infrastructure domains. If the role is network-aligned, review core networking protocols and troubleshooting frameworks. If it is defense-aligned, brush up on relevant compliance and engineering standards.

Problem-Solving & Troubleshooting – Interviewers want to see a structured, logical approach to solving complex, ambiguous problems. Whether you are debugging a network protocol or designing an enterprise system, walk your interviewers through your methodology step-by-step, highlighting how you isolate variables and validate your assumptions.

Client & Stakeholder Communication – As a consultant or contractor, you will often interact directly with government clients. You must demonstrate that you can explain complex technical concepts to non-technical stakeholders, manage client expectations professionally, and represent the company well on-site.

Adaptability & Clearance Readiness – Working in a government contracting environment requires a high degree of patience, adaptability, and compliance. Be prepared to discuss your experience or comfort level with background investigations, security clearance processes, and working within physical security constraints.

The hiring process at Sra Group is structured to evaluate your technical capabilities, cultural fit, and suitability for specialized client environments. Because the company supports various federal agencies and defense programs, the exact structure of your interview loop can vary depending on the specific contract and clearance requirements of the role.

The process typically begins with an initial screening by a corporate recruiter to review your resume, salary expectations, and basic qualifications. This is usually followed by a technical phone interview with a project manager, lead engineer, or technical director. This phone screen focuses on your core engineering skills, domain knowledge, and past project experience.

If you pass the phone screening, you will progress to a more comprehensive panel interview, which may be conducted virtually or in person at an Sra Group office or secure facility. This stage often involves deep-dive technical questions, systems design discussions, and behavioral evaluations with multiple team members, technical leads, and sometimes the end client.

This timeline illustrates the typical progression from your initial application to the final offer. Use this visual guide to pace your preparation, ensuring you focus on high-level resume alignment early on, deep technical concepts during the screening phase, and system-level design and behavioral preparation for the panel stage.

Network Architecture and Troubleshooting

For infrastructure and communications-focused software roles, Sra Group places immense value on your understanding of network layers and real-time communication protocols. You are expected to possess strong diagnostic skills to resolve complex connectivity issues.

Be ready to go over:

• OSI Model Diagnostics – Methodically isolating communication failures from the physical layer up to the application layer.
• Telephony & VoIP Protocols – Deep understanding of SIP, H.323, and MGCP call flows, signaling, and session management.
• Network Debugging Tools – Analyzing packet captures, interpreting system logs, and diagnosing routing or gateway anomalies.
• Advanced concepts (less common) – High-availability network designs, cryptographic protocol overhead, and hardware-level network interface card (NIC) optimization.

Example scenarios:

• "Walk us through how you would diagnose a dropped call issue occurring between two separate secure networks."
• "Describe a time you had to debug a complex network routing issue where packet loss was occurring intermittently."

Core Software Engineering and Systems Integration

If your role focuses on application development, your interviewers will evaluate your coding standards, architectural design capabilities, and experience integrating disparate software systems.

Be ready to go over:

• Object-Oriented Programming – Writing clean, modular, and maintainable code, primarily in Java or other enterprise-grade languages.
• Systems Integration – Designing robust APIs, managing data pipelines, and connecting legacy systems with modern cloud architectures.
• Concurrency & Performance – Developing thread-safe applications and optimizing resource utilization under heavy workloads.
• Advanced concepts (less common) – Microservices orchestration in secure, air-gapped environments and specialized hardware-software interface development.

Example scenarios:

• "How would you design a highly available, secure data ingestion service that processes real-time feeds from multiple external sources?"
• "Explain your approach to ensuring thread safety in a multi-threaded backend processor without sacrificing throughput."

Defense & Government Compliance

For specialized defense and maritime engineering roles, your familiarity with military standards and strict certification processes is a primary evaluation area.

Be ready to go over:

• Safety Certifications – Navigating compliance standards such as the US Navy P-9290 certification for manned submersibles.
• Secure Development Lifecycle – Adhering to federal security guidelines, vulnerability remediation, and defense-in-depth principles.
• Quality Assurance – Rigorous testing methodologies, configuration management, and system validation in highly regulated environments.

Example scenarios:

• "Describe your experience managing software requirements under strict military or government classification standards."
• "How do you approach software verification and validation when physical testing of the target hardware is highly restricted?"
