Preparing for an interview at Major League Baseball (MLB) requires a balanced approach. You must demonstrate deep technical competence while also showcasing the soft skills necessary to thrive in a highly collaborative, fast-moving environment.

Role-Related Knowledge – You must have a strong grasp of edge security concepts, including WAF configurations, CDN management, and DDoS mitigation. Interviewers will evaluate your understanding of web protocols, cloud security, and modern infrastructure-as-code deployment practices. Be ready to explain the "why" behind your architectural decisions.

Problem-Solving & Incident Response – Security engineering is highly dynamic. You will be evaluated on how you approach ambiguous, fast-evolving challenges, such as live security incidents. Focus on explaining your structured methodology: how you gather data, isolate variables, mitigate immediate threats, and implement long-term preventative measures.

Communication & Collaboration – Security cannot exist in a vacuum. You must be able to partner effectively with platform engineers, software developers, and product managers. Interviewers look for candidates who can advocate for strong security practices without becoming a bottleneck to innovation and product delivery.

Adaptability & Presence – Because MLB utilizes automated video screening platforms in its initial hiring phases, your ability to deliver clear, concise, and structured answers directly to a camera is critical. Showing confidence, managing your pacing, and maintaining an engaging presence online are vital evaluation criteria.

The interview process for a Security Engineer at Major League Baseball (MLB) is streamlined but requires careful preparation, particularly in the early stages. The process is designed to assess your technical baseline and behavioral fit before moving to deep-dive conversations with the engineering team.

The journey begins with an automated video screening process, often hosted on platforms like HireVue. In this stage, you will log into an online recording platform where you will be presented with a series of pre-recorded or text-based questions. There is no live interviewer present; instead, you will record your answers on camera within a set time limit. Candidates often report that this stage can feel structured and highly automated, featuring a mix of behavioral questions, basic cybersecurity concepts, and occasional lighthearted icebreaker questions.

If you pass the automated screening, you will move to the final round of interviews. This stage typically consists of a deep-dive interview with the hiring manager and key members of the security engineering team. This round is highly interactive, focusing on your past experiences, technical deep dives into edge security, and situational scenarios designed to test your real-world problem-solving abilities.

The timeline above illustrates the standard progression from your initial application to the final hiring decision. Candidates should use this visual roadmap to pace their preparation, ensuring they master the unique demands of the automated video screen before pivoting to deep-dive technical and architectural study for the final round.

To succeed in the MLB interview process, you must understand exactly how you are being evaluated across key competency areas.

Automated Video Interview Performance

This initial stage is where many candidates struggle due to the lack of live human feedback. The system evaluates your clarity, structure, and communication style.

Be ready to go over:

• The STAR Method – Structuring your behavioral answers using Situation, Task, Action, and Result to keep them concise and impactful.
• Time Management – Delivering complete answers within the platform's strict time limits (usually 2 to 3 minutes per question).
• Camera Presence – Maintaining eye contact with the camera, speaking at a steady pace, and projecting confidence.

Example scenarios:

• "Describe a challenging technical project you completed. What made it difficult and how did you succeed?"
• "How do you stay up-to-date with the latest cybersecurity threats and edge security technologies?"

Edge Security & Traffic Management

As an Edge Security Platform Engineer, your core technical evaluation will center on your ability to secure the perimeter of a high-traffic media network.

Be ready to go over:

• WAF Rule Tuning – How to write, test, and deploy Web Application Firewall rules to block malicious payloads while ensuring legitimate user traffic flows freely.
• CDN Integration – Securing content delivery pipelines, managing SSL/TLS certificates at scale, and configuring secure caching behaviors.
• DDoS Mitigation – Implementing rate limiting, geo-blocking, and behavioral analysis to block large-scale infrastructure and application-layer attacks.
• Advanced concepts – Any experience with Anycast routing, BGP hijacking protection, or edge compute security (such as running secure code at the edge via Cloudflare Workers or Fastly Compute@Edge).

Example scenarios:

• "Our streaming platform is experiencing a sudden, distributed layer 7 attack targeting our login endpoints. Walk us through your immediate mitigation steps."
• "How would you design a secure, automated pipeline to deploy updated WAF rules across multiple cloud providers simultaneously?"

Foundational Cybersecurity & Systems

Beyond edge-specific technologies, you must demonstrate a rock-solid understanding of general security engineering principles.

Be ready to go over:

• Network Protocols – Deep knowledge of HTTP/S, DNS, TCP/IP, and how secure handshakes occur.
• Identity & Access Management (IAM) – Securing APIs and applications using modern protocols like OAuth 2.0, OIDC, and SAML.
• Infrastructure as Code (IaC) – Using tools like Terraform to deploy secure, repeatable infrastructure environments.

Example scenarios:

• "Explain how DNSSEC works and why it is important for protecting our digital brand."
• "How do you ensure secret keys and API credentials are not exposed during automated code deployments?"
