As a Data Engineer at Coursera, you are responsible for designing, building, and maintaining scalable data pipelines that support the company’s online learning platform. You work closely with data scientists, analysts, and product teams to ensure reliable data flow and accessibility for analytics and reporting. Typical tasks include optimizing database performance, integrating diverse data sources, and implementing data quality measures. This role is essential for enabling data-driven decision-making and improving user experiences, directly contributing to Coursera’s mission of expanding access to world-class education.

2.1 Stage 1: Application & Resume Review

The process begins with a thorough review of your application and resume by Coursera’s recruiting team. They look for strong evidence of data engineering fundamentals, including expertise in SQL, experience with designing and maintaining data pipelines, proficiency in Python, and hands-on work with ETL processes and large-scale data systems. Highlighting your experience with scalable data architecture, data modeling, and cloud-based solutions will help your application stand out. Make sure your resume showcases relevant projects, quantifiable impact, and familiarity with both structured and unstructured data environments.

2.2 Stage 2: Recruiter Screen

If your resume matches the requirements, you’ll typically have a 20–30 minute phone conversation with a recruiter or HR representative. This screen covers your motivation for applying, alignment with Coursera’s mission, and a high-level overview of your technical background. You’ll be asked about your experience with SQL, Python, and data pipeline development, as well as your ability to communicate complex technical concepts to non-technical stakeholders. Prepare by articulating your career trajectory, reasons for interest in Coursera, and ability to contribute to a collaborative, fast-paced environment.

2.3 Stage 3: Technical/Case/Skills Round

The next phase involves a technical assessment, which may be conducted as a live coding interview, an online assessment, or a take-home assignment. Expect to solve practical SQL queries, data modeling problems, and Python scripting tasks, such as designing a robust ETL pipeline, processing large datasets, or implementing data cleaning routines. You might also encounter object-oriented design (OOD) questions or be asked to build a scalable data ingestion or reporting pipeline. Emphasis is placed on your problem-solving approach, code quality, and ability to handle real-world data engineering scenarios. Practicing end-to-end pipeline design and demonstrating efficiency in handling large data volumes will be beneficial.

2.4 Stage 4: Behavioral Interview

This round is typically conducted by a hiring manager or a cross-functional partner. It focuses on your ability to collaborate, communicate technical insights clearly, and adapt to Coursera’s culture. You’ll be asked to share experiences working on complex data projects, overcoming challenges in data quality or pipeline failures, presenting technical findings to diverse audiences, and contributing to team goals. Prepare specific examples that illustrate your leadership, adaptability, and stakeholder management skills, especially in educational technology or similar domains.

2.5 Stage 5: Final/Onsite Round

The final round usually consists of a series of interviews (virtual or in-person) with data engineers, managers, and cross-functional stakeholders. This stage dives deeper into your technical expertise with whiteboard exercises, advanced SQL and Python challenges, data pipeline architecture discussions, and system design scenarios relevant to Coursera’s platform (such as building scalable solutions for course data or user analytics). You may also be asked to present a data engineering project or walk through a technical case study, demonstrating both your technical depth and your ability to communicate complex ideas effectively. Strong presentation skills and the ability to justify your design decisions are key.

2.6 Stage 6: Offer & Negotiation

Once you’ve successfully completed all interview rounds, the recruiter will reach out to discuss the offer package, including compensation, benefits, and potential start dates.
