The interview process for a Data Engineer at BBVA is designed to be thorough, technically rigorous, but ultimately very cordial and welcoming. Candidates consistently report that our interviewers go out of their way to make you feel comfortable, allowing you to showcase your true capabilities. The entire end-to-end process typically takes about a month, so patience and consistent engagement are key to your success.

Your journey will generally begin with an initial screening with our Human Resources team. During this stage, HR will explain the general policies of the bank, outline the day-to-day tasks of the role, and discuss high-level compensation and benefits. Following this, you will progress to technical interviews with the area managers and senior engineers. These sessions will dive deep into your technical capabilities, architectural thinking, and problem-solving skills through practical scenarios.

While the technical rounds are challenging and fun, be aware that the administrative stages can sometimes move slowly. If you are selected, the final offer generation and documentation phase can take over two weeks to finalize. We encourage you to stay in touch with your recruiter and use this time to prepare for your eventual onboarding.

This timeline illustrates the typical progression from your initial HR screening through the technical rounds and finally to the offer stage. You should use this visual to pace your preparation, focusing heavily on your technical and system design skills after passing the initial behavioral screen. Note that timelines can vary slightly depending on your specific region, such as Mexico City or Buenos Aires, but the core sequence remains consistent.

Data Architecture and Pipeline Engineering

As a Data Engineer, your primary responsibility is moving and transforming data efficiently and reliably. Interviewers will heavily evaluate your ability to design robust ETL (Extract, Transform, Load) and ELT pipelines. Strong performance in this area means you can design architectures that scale, recover gracefully from failures, and ensure high data fidelity.

Be ready to go over:

• Batch vs. Streaming Processing – Understanding when to use scheduled batch jobs versus real-time streaming, and the tools associated with each.
• Data Modeling – Designing schemas (e.g., Star, Snowflake) that optimize for both storage costs and analytical query performance.

As a Data Engineer at BBVA, your day-to-day work revolves around building and maintaining the critical infrastructure that allows our business to make data-driven decisions. You will be actively involved in designing, developing, and deploying scalable data pipelines that extract data from diverse internal systems, transform it according to business rules, and load it into centralized analytical environments. This requires a constant focus on data quality, ensuring that the information downstream users rely on is accurate, timely, and complete.

Collaboration is a massive part of your daily routine. You will work side-by-side with data scientists to prepare datasets for machine learning models, and with product managers to ensure reporting dashboards have the underlying data they need. You will also partner closely with software engineering teams to integrate data collection directly into customer-facing applications, ensuring a seamless flow of information from the user's mobile app directly into our data lakes.

Additionally, you will play a key role in modernization initiatives. Many of our teams are actively migrating legacy on-premise workloads to modern cloud architectures. You will be responsible for refactoring old processes, optimizing legacy SQL scripts, and implementing modern CI/CD practices for data pipelines. Through all of this, you will maintain strict adherence to BBVA's security and governance protocols, protecting our customers' data at every step.

To thrive as a Data Engineer at BBVA, you need a solid foundation in software engineering principles combined with specialized knowledge of data systems. We look for candidates who can balance rapid development with the rigorous quality standards required in the banking sector.

• Must-have technical skills – Advanced proficiency in SQL and at least one programming language (Python, Scala, or Java). You must have hands-on experience building ETL/ELT pipelines and working with relational databases.
• Must-have experience – Typically, 3+ years of professional experience in data engineering, software engineering, or a closely related technical field. You should have a proven track record of deploying code to production environments.
• Nice-to-have technical skills – Experience with distributed computing frameworks (Apache Spark, Kafka), cloud platforms (AWS, GCP, Azure), and orchestration tools (Airflow). Familiarity with financial data models is a significant plus.
• Soft skills – Strong analytical thinking, clear communication, and the ability to manage expectations with business stakeholders. You must be comfortable working in an agile environment and adapting to shifting priorities.
