An Engineering Manager at Viasat plays a pivotal role in shaping the future of global connectivity. Viasat is not just an internet service provider; it is a global communications powerhouse that designs, integrates, and operates high-capacity satellite networks, secure defense systems, and advanced commercial aviation connectivity platforms. As an Engineering Manager, you are responsible for leading multi-disciplinary engineering teams that build high-reliability systems, embedded software, network protocols, and ground control stations that keep millions of users connected across land, sea, and air.

Your impact in this role is both immediate and far-reaching. You will guide your team through complex technical challenges, such as optimizing data throughput over high-latency satellite links, migrating legacy architectures to modern cloud-native infrastructures, and implementing rigorous automation pipelines. At Viasat, engineering management is a balance of deep technical stewardship and people-first leadership. You will work closely with product managers, system architects, and cross-functional global teams to translate high-level business objectives into robust, scalable software solutions.

What makes this role uniquely compelling is the sheer scale and complexity of the problem space. You will manage engineers working on next-generation satellite constellations (like ViaSat-3) and secure communication systems for tactical defense. Success in this position requires a leader who is as comfortable diving into low-level code or network packet analysis as they are coaching engineers, unblocking dependencies, and driving a culture of continuous improvement and engineering excellence.

The interview questions you will face at Viasat are designed to evaluate your technical foundation, architectural thinking, and people management strategies. These questions are drawn from real candidate experiences and reflect the actual scenarios you will encounter during your discussions with hiring managers and peer engineers. Use these groupings to identify patterns and prepare your responses.

System Design & Architecture

These questions assess your ability to design resilient, scalable systems and defend your architectural choices under pressure.

• Describe your last major project in detail. Walk us through the architecture, and explain why you chose specific design patterns or technologies over alternative solutions.
• How do you design systems that remain resilient in the face of network instability, high latency, or packet loss?

Preparing for an Engineering Manager interview at Viasat requires a balanced approach. You cannot rely solely on your leadership experience; you must also sharpen your technical edge.

Here are the key evaluation criteria that the hiring team will focus on:

Technical Depth & System Architecture – You must prove that you can still engage deeply with engineering concepts. Viasat interviewers will push you to explain the "why" behind your past architectural decisions, evaluating your understanding of trade-offs, resource constraints, and system design principles.

People Leadership & Talent Development – You will be evaluated on your ability to build, mentor, and retain high-performing teams. Be ready to discuss how you handle underperformance, how you foster career growth for senior engineers, and how you cultivate a collaborative, inclusive team culture.

Execution & Delivery – Viasat looks for managers who can deliver complex projects on time. You need to demonstrate strong project management skills, including risk mitigation, resource allocation, and cross-functional collaboration across different time zones.

Cultural Alignment & Adaptability – The company culture is highly collaborative and relatively informal. Interviewers look for leaders who are approachable, open to feedback, and capable of navigating ambiguity while maintaining a positive, solution-oriented mindset.

The interview process for an Engineering Manager at Viasat is thorough and highly collaborative, designed to ensure a mutual fit. Candidates should prepare for a multi-stage journey that can span several weeks, and sometimes up to a couple of months, due to the coordination required across global teams. The process typically begins with an initial phone screen with a recruiter to discuss your background, career goals, and general alignment with the role.

Following the initial screen, you will enter a series of technical and managerial rounds. This usually includes a deep-dive architectural session focusing on your past projects, followed by hands-on technical interviews covering data structures, algorithms, and networking fundamentals. For many teams, you will also participate in a telephonic or video round with international collaborators (such as US-based teams if you are interviewing in India, or vice versa) to evaluate your cross-cultural communication and global collaboration skills. The final stages often involve a series of 1:1 panels with peer managers, direct reports, and senior leadership.

The timeline above outlines the typical progression from your first contact with HR to the final decision. While the sequence of technical and behavioral rounds is structured to evaluate your comprehensive skill set, the exact timing can vary depending on the location of the hiring team and the availability of cross-site interviewers. Use this timeline to pace your preparation, ensuring you allocate sufficient time to both technical review and behavioral storytelling.

To succeed in the Viasat interview loop, you must understand the specific competencies being tested in each core area. Below is a detailed breakdown of the primary evaluation domains.

Architecture & System Design

This area evaluates your ability to design robust, high-availability systems that can handle the unique constraints of satellite and global network infrastructures. Viasat systems must operate with high reliability under challenging physical conditions, making trade-off analysis a critical skill.

Be ready to go over:

• System Trade-offs – Explaining why you chose a specific technology or architecture over another (e.g., relational vs. non-relational databases, or synchronous vs. asynchronous communication).
• Scalability & Latency – How to design systems that handle massive data loads while minimizing latency over satellite links.
• Legacy Migration – Strategies for refactoring or migrating legacy systems to modern, cloud-native platforms with zero downtime.

Advanced concepts (less common):

• Real-time operating systems (RTOS) and embedded system architectures.
• Managing satellite link budgets and handling high packet loss at the software layer.

Example questions or scenarios:

• "Walk me through the design of a system you built that had to scale to support millions of concurrent connections. What were the primary bottlenecks, and how did you resolve them?"
• "How would you design a telemetry data ingestion system that collects real-time diagnostics from thousands of inflight aircraft?"

Core Technical Proficiency (C/DS & Networking)

Even in a management role, Viasat expects you to maintain a solid technical foundation. You will face questions that test your understanding of data structures, memory optimization, and core networking protocols.

Be ready to go over:

• Memory-Efficient Algorithms – Utilizing low-level data structures, such as bitmaps, to solve problems with minimal memory footprints.
