Clean Code & Craftsmanship – At Tla, we have a strong passion for clean code. You should be prepared to discuss SOLID principles, design patterns, and unit testing strategies. Be ready to explain how you write self-documenting code and how you approach refactoring legacy systems.

System Design & Microservices – We build scalable web applications. You should understand how to design RESTful WebAPIs, manage microservices communication, and integrate frontend frameworks like Angular with backend services.

Behavioral Articulation – Be ready to talk in detail about your past roles, university projects (if applicable), and career achievements. We want to hear about real-world scenarios where you solved tough problems, worked under pressure, or took the initiative to improve a process.

Communication & Collaboration – We value a friendly, open, and collaborative personality. Throughout the process, focus on explaining your thought process clearly, asking clarifying questions, and showing enthusiasm for the product and technology.

The interview process for a Software Engineer at Tla is a relaxed, friendly, and structured three-stage journey. We have designed this process to ease you into the team culture while giving you an authentic opportunity to showcase both your personality and your technical prowess.

The first stage is a Microsoft Teams session with two members of our engineering team. This round focuses on introductions, easing you into the process, and understanding your background. The second stage is a take-home technical test completed in your own time, which our candidates frequently describe as highly engaging and relevant to our actual product domain. The final stage is a technical review where you will walk through your code with the team, followed by a general conversational interview to ensure alignment on both sides.

The timeline above outlines the typical progression of our three-stage interview process. Candidates should use this structure to pace their preparation, focusing first on behavioral storytelling, then on clean coding practices for the take-home test, and finally on architectural justification for the code review. While the stages remain consistent, the technical depth of the discussions will scale based on the seniority of the role you are applying for.

To succeed at Tla, you need to understand exactly what your interviewers are looking for during each interaction. We evaluate candidates across three primary dimensions to ensure a strong technical and cultural fit.

Clean Code & Technical Test

Our take-home technical test is the cornerstone of our evaluation. We want to see how you write code when you are not under the pressure of a live coding environment. We look for elegant, maintainable, and well-structured code.

Be ready to go over:

• SOLID Principles – How you apply these principles to make your code modular and easy to extend.
• Unit Testing – Your approach to writing meaningful tests that cover critical business logic.
• Naming & Readability – Writing self-documenting code that any engineer on the team can easily understand.
• Advanced concepts (less common) – Domain-Driven Design (DDD) patterns and complex refactoring strategies.

Example scenarios:

• Refactoring a tightly coupled piece of legacy code into a clean, testable service.
• Designing a clear and intuitive folder and project structure for your take-home submission.

Microservices & Architecture

Our systems rely heavily on modern backend frameworks and microservices architectures. We want to ensure you understand how to build services that are both performant and resilient.

Be ready to go over:

• .NET Core & WebAPI – Your familiarity with building modern, lightweight APIs.
• Microservices Communication – How services communicate with each other, whether through synchronous HTTP calls or asynchronous messaging.
• Frontend Integration – How you structure APIs to be easily consumed by modern frontend frameworks like Angular.
• Advanced concepts (less common) – Containerization (Docker), API Gateway patterns, and distributed caching.

Example scenarios:

• Explaining how you would design a new microservice to handle a high volume of incoming leads.
• Discussing how you secure APIs and handle cross-origin resource sharing (CORS) with a frontend application.

Behavioral & Team Fit

We pride ourselves on having a friendly, considerate, and highly collaborative team. We look for engineers who are not only technically skilled but also great teammates who elevate those around them.

Be ready to go over:

• Handling Pressure – Real examples of how you navigated tight deadlines or production outages.
• Going Above and Beyond – Stories of times you took ownership of a problem outside your immediate scope.
• Collaboration – How you work with product managers, QA engineers, and other developers to deliver value.

Example scenarios:

• Describing a situation where you had a technical disagreement with a colleague and how you resolved it constructively.
• Sharing an achievements-focused overview of your career and your personal growth goals.

As a Software Engineer at Tla, your day-to-day work will be highly collaborative and focused on delivering high-quality software. You will be embedded in a cross-functional team, working closely with other engineers, product owners, and stakeholders to design and implement new features.

A significant portion of your time will be spent writing clean, maintainable C# code using the latest .NET Core framework. You will build and optimize WebAPI microservices, design database schemas, and integrate your backend services with Angular frontends. You will also participate in daily standups, sprint planning sessions, and retrospectives, contributing to the continuous improvement of our agile processes.

In addition to feature development, you will play an active role in maintaining system health.
