The recruiter will also explain the job responsibilities and company culture, and you may have an opportunity to ask any preliminary questions.

2. Technical Screen (Coding/Problem Solving)

Duration: 1 hour
Focus: The technical screen often involves coding questions that test your SQL, Python, and data engineering skills. You might be asked to write code or solve problems related to data extraction, manipulation, or reporting.

Example Problems:

• “Write an SQL query to select the top 5 performing salespeople based on the number of transactions.”
• “Explain the steps you would take to optimize a slow-running SQL query on a large dataset.”
• “Given a dataset with missing values, how would you approach cleaning and preprocessing the data?”

Tools/Skills Tested:

• Python (Pandas, NumPy)
• SQL (Redshift, MySQL)
• Data pipeline frameworks (AWS Glue, CI/CD)
• Reporting tools (Tableau, QuickSight)

3. Onsite/Virtual Interview (Multiple Rounds)

Duration: 3-4 hours (broken into several sessions)
Focus: This round assesses your technical expertise, problem-solving ability, and your experience working with cross-functional teams. The sessions might include:

• Coding Challenge: Focuses on data manipulation and query optimization.
• System Design: You’ll be asked to design a data pipeline or architecture that supports scalable analytics.
• Behavioral Interview: Focuses on your ability to collaborate with product managers, analysts, and engineers.

Example Technical Questions:

• “How would you design a data mart to support reporting for a large e-commerce company?”
• “Describe how you would improve the performance of a data pipeline that is experiencing slow data processing times.”
• “Explain the trade-offs between using batch vs. real-time data processing in a large-scale analytics environment.”

Example Behavioral Questions:

• “Tell us about a time when you had to collaborate with a product team to define analytics requirements. How did you ensure that their needs were met?”
• “Describe a situation where you encountered a technical challenge in data modeling. How did you approach solving it?“

4. Final Round (Culture Fit and Leadership Interview)

Duration: 1 hour
Focus: This interview assesses how well you align with Remitly’s culture and values. Expect questions that explore your leadership potential, collaboration style, and long-term vision.

• “How do you handle situations where there are conflicting priorities among team members or stakeholders?”

Key Skills and Technologies Tested

For the Senior Analytics Engineer role, here are the key areas of expertise and technologies you’ll need to be proficient in:

• Data Engineering: You should be comfortable working with data pipelines, dimensional data modeling, ETL processes, and data optimization techniques.
• Programming: Strong knowledge of Python (especially libraries like Pandas and NumPy) and SQL for querying large datasets is essential. You may also be asked to demonstrate your ability to work with AWS services like Glue and Redshift.
• Reporting & Dashboards: Experience with tools like Tableau, QuickSight, or similar is important for visualizing data and presenting analytical insights to stakeholders.
• DataOps/CI/CD: Knowledge of continuous integration and deployment processes, particularly in the context of data engineering, is highly valued.
• Collaboration: The role involves significant interaction with cross-functional teams, so your ability to manage stakeholder relationships, communicate effectively, and lead projects is key.

Behavioral and Problem-Solving Examples

Here are some examples of how you can respond to behavioral questions based on real-world situations:

Managing Cross-Functional Teams:

Example Question: “Can you provide an example of how you have led cross-functional teams to successfully deliver complex projects on time and within budget?”
Response:
“In my previous role, I led a project to build a reporting pipeline for the sales and marketing teams. The project involved coordinating with both teams to gather requirements and ensure that the data was formatted correctly. We faced challenges with different data sources, but I facilitated regular communication between teams, prioritized tasks based on business impact, and ensured timely delivery. The project was completed ahead of schedule, and the dashboard we created improved the marketing team’s ability to analyze customer data in real-time.”

Handling Conflicting Priorities:

Example Question: “How do you handle conflicting priorities among stakeholders?”
Response:
“In situations with conflicting priorities, I begin by understanding the key drivers for each stakeholder. I try to align their priorities with the overall business goals. In one instance, a product team wanted a feature that could delay our data pipeline rollout, while the engineering team prioritized system stability. I facilitated a meeting where both teams discussed the trade-offs, and we agreed to implement the feature in phases. This approach allowed us to meet both priorities without compromising the project’s timeline or quality.”

Automation and Optimization:

Example Question: “Explain your approach to identifying opportunities for automation within the analytics lifecycle.”
Response:
“I focus on repetitive tasks that are prone to human error. For example, I automated data quality checks in the ETL pipeline, reducing manual monitoring efforts. I used Python scripts to perform daily validation of incoming data and set up alerts when discrepancies were found. This reduced the time spent on manual checks and improved the accuracy of our reports.”

Final Tips for Preparation:

• Brush Up on Data Modeling: Be ready to discuss dimensional modeling, star schemas, and other common analytics design patterns.
• Review Cloud Technologies: Familiarize yourself with AWS Glue, Redshift, and other cloud-based tools used at Remitly.
• Prepare for System Design: Practice designing scalable data pipelines and data marts, considering factors like performance optimization and data consistency.
• Be Ready for Coding Challenges: While the focus may be more on your analytics skills, expect some coding challenges that test your problem-solving and algorithmic thinking.
