AVIV Group Backend Engineer interview questions & guide 2026

The salary data provided represents typical compensation ranges for this role, reflecting both market standards and the seniority level of the position. Candidates should interpret these figures as a baseline for negotiation and understand that total packages often include additional benefits and equity components. Use this information to benchmark your expectations and align them with your professional experience and the specific requirements of the role.

Our interview process is designed to evaluate your technical competency, your ability to reason through architectural trade-offs, and your approach to collaborative problem-solving. The following questions are representative of the patterns you will encounter during your assessment.

Technical and System Design

These questions test your ability to design efficient, scalable systems and your understanding of how to optimize existing infrastructure.

• How would you improve the efficiency of an API?
• Explain the trade-offs between different architectural approaches for a high-traffic service.

Preparation for AVIV Group requires a blend of hands-on coding practice and a strong grasp of architectural fundamentals. You should be prepared to not only write code but to explain the logic and trade-offs behind your decisions.

Technical Proficiency – This measures your ability to write clean, maintainable code and your comfort with debugging. You will be evaluated on your ability to work within existing codebases and your speed in identifying and fixing issues.

System Design Thinking – We look for candidates who understand how components interact in a distributed environment. You should be able to discuss latency, throughput, and how to scale services to meet user demand.

Communication and Clarity – Your ability to articulate your thought process is as important as the code itself. During technical discussions, focus on explaining the "why" behind your design choices and the trade-offs you considered.

The interview journey at AVIV Group is structured to be transparent and collaborative, focusing on your real-world problem-solving abilities. You can expect a process that moves from initial screening to hands-on technical evaluation, concluding with a managerial discussion. The pace is generally efficient, and we emphasize finding engineers who can thrive in a collaborative, product-focused environment.

Our philosophy is to minimize "trick" questions and instead focus on challenges that mirror the daily work of our engineering teams. Whether through live-coding sessions or project-based assessments, we want to see how you think, how you handle feedback, and how you approach complex systems.

This visual timeline illustrates the typical progression from an initial HR conversation to technical deep dives and final leadership reviews. Candidates should use this as a roadmap to manage their preparation energy, focusing on coding fundamentals early in the process and architectural strategy toward the end. Note that the specific sequence can occasionally shift based on team requirements or hiring urgency.

Architectural Trade-offs

We evaluate your ability to think critically about system design. Strong candidates don't just provide a "correct" solution; they discuss the pros and cons of different approaches, such as consistency vs. availability or monolithic vs. microservice structures.

• Efficiency and Scalability – Understanding how to optimize database queries and API responses.
• System Reliability – Discussing strategies for error handling and system resilience.
• Trade-off Analysis – Being able to justify why one technology or pattern was chosen over another.

Example scenarios:

• "How would you redesign this service to handle a 10x increase in traffic?"
• "What are the risks of using this specific database architecture?"

Code Quality and Maintenance

Working at AVIV Group often involves contributing to established systems. We evaluate how you read, understand, and improve existing code.

• Testing Standards – Proficiency in writing and maintaining unit and integration tests.
• Debugging Skills – The ability to systematically identify the root cause of a bug in an unfamiliar codebase.
• Code Readability – Writing code that is clean, modular, and easy for other team members to maintain.

As a Backend Engineer, your primary responsibility is to ensure the reliability and performance of our services. You will spend a significant portion of your time writing and reviewing code, participating in technical design sessions, and collaborating with frontend engineers and product managers to deliver seamless user experiences.

You will be expected to take ownership of features from conception through to deployment. This includes writing technical specifications, conducting code reviews, and monitoring the performance of your services in production. By working closely with cross-functional partners, you will ensure that the technical solutions you build align with the broader business objectives of the AVIV Group.

A successful candidate for this role typically brings a strong foundation in backend development, coupled with a pragmatic approach to problem-solving.

• Must-have skills: Proficiency in at least one major backend language (e.g., Java, Go, Python, or Node.js), strong understanding of RESTful APIs, and experience with relational databases.
• Nice-to-have skills: Experience with cloud infrastructure (AWS/GCP), containerization (Docker/Kubernetes), and event-driven architectures.
• Experience level: A balance of hands-on coding experience and the ability to contribute to system design discussions is essential.

Q: How much time should I spend preparing? A: Most candidates find that 2–3 weeks of focused practice on system design and coding exercises is sufficient to feel confident.

Q: What differentiates successful candidates? A: Successful candidates are those who communicate their thought process clearly and show a genuine interest in the business problems we are solving.

Q: Is the technical interview focused on algorithms or real-world tasks? A: We lean heavily toward real-world scenarios, such as bug fixing and API design, rather than abstract algorithm puzzles.

Q: What is the culture like at AVIV Group? A: We value collaboration, transparency, and a focus on impact; we look for engineers who enjoy working in agile, cross-functional teams.

• Think out loud: During live coding or system design, talk through your reasoning so the interviewer can follow your logic.
• Ask clarifying questions: If a requirement seems ambiguous, ask for more details before jumping into a solution.
• Focus on trade-offs: Never suggest a solution without mentioning why you chose it over the alternatives.
• Review your previous work: Be prepared to discuss the technical challenges and lessons learned from your past projects.

The Backend Engineer role at AVIV Group offers a unique opportunity to shape the technology behind major property marketplaces. By focusing on your ability to design scalable systems, write maintainable code, and communicate effectively, you will be well-positioned to succeed in our interview process. Remember that we are looking for partners in problem-solving, not just executors of tasks.
