Juspay Technologies Site Reliability Engineer interview questions & guide 2026

The following questions are representative of the patterns identified in recent Juspay Technologies interviews for Site Reliability Engineer candidates. While specific technical hurdles may vary based on your experience level, the core focus remains on foundational knowledge and your ability to apply those concepts to real-world scenarios.

Technical Fundamentals

These questions test your core knowledge of the operating systems and network protocols that power our infrastructure.

• How do you remove a file from a directory in a Linux environment?
• What are the specific steps to navigate to a target directory?

Preparation for Juspay Technologies should be focused on depth rather than breadth. You must demonstrate that you understand how individual components—such as a Linux command or a networking protocol—fit into the larger picture of a high-scale payment system.

Role-related knowledge – You are expected to have a mastery of Linux, networking, and database internals. Interviewers will look for your ability to explain these concepts clearly and apply them to troubleshooting scenarios.

Problem-solving ability – We value engineers who can break down complex, ambiguous problems into logical steps. When presented with a case study or a system design challenge, structure your response by identifying the constraints first, then proposing a scalable, fault-tolerant solution.

Execution and Grit – Our processes, including the Learnathon or hackathon stages, are designed to test how you work under pressure and how you navigate limited documentation or support. Stay focused on delivering functional, well-reasoned code or designs, even when the environment feels challenging.

The interview process at Juspay Technologies is designed to test both your theoretical knowledge and your practical ability to build under time constraints. You should expect a rigorous, multi-stage evaluation that begins with high-volume technical screening and transitions into more collaborative, project-based assessments.

This timeline illustrates the progression from initial screening to final assessment. Use this to pace your preparation, ensuring you have refreshed your fundamental technical knowledge before the screening rounds and prepared your environment for the more intensive technical and collaborative stages.

Linux and Operating Systems

At Juspay Technologies, Linux is the backbone of our operations. You must be comfortable with the command line and understand how processes interact with the kernel.

Be ready to go over:

• File system navigation and permissions.
• Process management and resource monitoring (CPU, Memory, I/O).

As a Site Reliability Engineer, your primary objective is to maintain the integrity and availability of the Juspay Technologies stack. You will spend your time automating manual operational tasks, improving monitoring systems, and responding to incidents that could affect transaction processing.

You will collaborate closely with software engineering teams to ensure that new code is reliable and performant before it hits production. This involves participating in architecture reviews, setting up CI/CD pipelines, and writing infrastructure-as-code. You are the bridge between development and operations, ensuring that the system is not only functional but also resilient to failure.

A successful candidate for the Site Reliability Engineer role at Juspay Technologies balances deep technical expertise with a high degree of ownership.

• Must-have skills: Proficient in Linux/Unix environments, strong understanding of networking protocols (TCP/IP, HTTP/S, DNS), experience with database management, and a solid grasp of operating system fundamentals.
• Nice-to-have skills: Experience with cloud infrastructure (AWS/GCP), containerization (Docker, Kubernetes), and scripting languages like Python or Go for automation.
• Experience level: While requirements vary, candidates are expected to have a demonstrated track record of managing or supporting production systems.

Q: How long should I spend preparing for the technical screening? A: Dedicate at least 2–3 weeks to reviewing core computer science fundamentals, specifically Linux and Networking. Given the MCQ-heavy nature of the initial rounds, speed and accuracy are as important as depth.

Q: What is the most common reason candidates fail the technical interview? A: A lack of clarity in explaining the "why" behind their technical decisions. It is not enough to know the command; you must explain how it impacts system stability.

Q: How can I prepare for the hackathon/Learnathon portion? A: Focus on building clean, modular, and well-documented code. Be prepared for ambiguity and focus on delivering a minimum viable solution that meets all requirements before optimizing.

• Prioritize Speed: The initial MCQ rounds are time-constrained. Practice solving technical problems under strict time limits to build your confidence.
• Master the Basics: Do not overlook the "simple" questions. Many candidates get caught off-guard by fundamental Linux or networking questions because they focused too heavily on complex architecture.
• Communicate Your Process: During technical interviews, talk through your thought process aloud. Even if you don't reach the perfect answer, the interviewer wants to see how you approach a problem.

The Site Reliability Engineer role at Juspay Technologies is a challenging, high-impact position that requires a disciplined approach to systems engineering. By mastering the fundamentals of Linux, networking, and distributed systems, and by demonstrating a clear, logical approach to problem-solving, you will position yourself as a strong candidate.
