Preparation for Sendbird should be rooted in a "customer-first" technical mindset. You must be prepared to articulate not just how you solve a problem, but why your solution is the most scalable and efficient for the customer.

Technical Depth You must demonstrate a mastery of API architecture and mobile/web development. Interviewers will look for your ability to "speak computer tech language" fluently. Be ready to dive into the details of HTTP, WebSockets, and SDK lifecycle management.

Problem-Solving Structure When faced with a technical scenario, do not jump straight to a solution. Clearly articulate your diagnostic process, how you isolate variables, and how you validate your hypothesis. Sendbird values engineers who think methodically under pressure.

Communication Clarity As a Customer Success Engineer, you are the face of the company. You must show that you can simplify complex technical requirements for non-technical clients without losing accuracy. Effective communication is a key evaluation metric here.

The interview process at Sendbird is structured to be rigorous but transparent. Typically, you will begin with an initial HR or recruiter screen to discuss your background and career aspirations. This is followed by a series of technical interviews with hiring managers and team members, which may involve remote video calls or an onsite visit. The process is designed to evaluate both your technical problem-solving capabilities and your ability to navigate the complexities of client relationships.

This module outlines the typical stages of the Sendbird interview journey. You should interpret this as a roadmap for your preparation; each stage increases in technical intensity. Use this timeline to pace your study of API documentation and common troubleshooting scenarios, ensuring you are ready for the deep-dive technical discussions with hiring managers.

Technical Communication

Your ability to translate technical data into actionable advice is the cornerstone of this role. Strong candidates are those who can balance technical precision with extreme clarity.

Be ready to go over:

• Explaining technical roadblocks to non-developers.
• Managing expectations during service outages or technical limitations.
• Documenting solutions for internal knowledge bases.

Example questions or scenarios:

• "Explain to me how a JWT (JSON Web Token) works as if I were a Product Manager."
• "How do you handle a client who insists on a feature that is technically suboptimal for our platform?"

Technical Troubleshooting

You will be evaluated on your ability to isolate issues within a distributed system. You must be comfortable navigating logs and identifying patterns.

Be ready to go over:

• Network layer diagnostics (TCP/IP, TLS).
• API integration debugging (cURL, Postman).
• Cross-platform SDK behavior (React Native, iOS, Android).

Example questions or scenarios:

• "A client reports that messages are not being delivered in a specific region. What are your first three steps?"
• "How would you determine if an issue is caused by our backend or the client’s frontend implementation?"

As a Customer Success Engineer, your primary objective is to drive the successful adoption and ongoing health of Sendbird’s products. You will spend a significant portion of your day analyzing technical logs, reproducing client-reported bugs, and providing clear, concise technical guidance to developers at our client companies.

You will work closely with the engineering team to escalate critical bugs and with the sales/account management teams to provide technical insights that ensure long-term client retention. You will also be responsible for creating technical documentation, such as FAQs or integration guides, based on the recurring challenges you observe in the field. Success in this role is defined by your ability to minimize the time-to-resolution for client issues and to proactively prevent future technical hurdles.
