Tiger Analytics Data Engineer Interview Questions: Complete Guide to Crack Your Next Data Role

Landing a data engineering role at Tiger Analytics can be challenging if you’re not prepared for the technical and managerial rounds. From SQL queries to Spark optimization, understanding the types of questions and how to answer them can set you apart.

I’ve guided many students and professionals through similar interviews, and I’ve noticed that success comes from a mix of conceptual clarity, practical knowledge, and storytelling during interviews. In this post, I’ll walk you through real Tiger Analytics Data Engineer interview questions and share strategies to answer them confidently.

Interview Procedure

The interview process at Tiger Analytics usually has three rounds:

  1. Round 1 (L1) – Technical screening with SQL and Spark questions.

  2. Round 2 (L2) – Deep-dive into project experience, data pipelines, and advanced SQL/Spark problems.

  3. Managerial Round – Focuses on project management, teamwork, mentorship, and problem-solving skills.

Round 1 (L1) – Core Technical Questions

This round tests your fundamentals of SQL, Spark, and big data frameworks.

Key questions include:

  • Explain the difference between INNER JOIN, LEFT JOIN, and RIGHT JOIN, and how many rows each produces.

  • Difference between RANK(), DENSE_RANK(), and ROW_NUMBER() in SQL.

  • How Spark works internally when a job is submitted.

  • Compare Spark vs MapReduce in handling large datasets.

  • SQL query to find the second-highest salary in a table.

  • Role of SparkContext in a Spark application.

  • Techniques to optimize Spark jobs for better performance.

Tip for Candidates: Use real examples from projects you’ve handled. Explaining why you chose a specific join type or window function demonstrates practical understanding.

Round 2 (L2) – Advanced Technical and Project-Based Questions

The second round focuses on hands-on SQL and Spark knowledge, your experience with large datasets, and problem-solving in real-world scenarios.

Example questions include:

  • Write queries to list high-value customers or those who spent the most last month.

  • Join two data frames with different schemas where one has more rows.

  • How you handled challenges in large-scale data processing in previous projects.

  • Use of window functions to calculate running totals or rank data.

  • Techniques to handle missing or corrupted data in distributed systems.

  • Differences between batch processing and real-time data processing.

  • Designing incremental data pipelines and ensuring scalability.

  • Strategies to handle skewed data in Spark and monitor pipelines effectively.

Tip: Emphasize end-to-end solutions you implemented. Recruiters value candidates who can design, optimize, and maintain data pipelines independently.

Managerial Round – Leadership and Project Handling

The final round assesses soft skills, leadership, and problem-solving.

Typical questions include:

  • Explain a previous project in detail, including objectives, technologies used, and challenges faced.

  • How you prioritize tasks and manage deadlines across multiple projects.

  • Experience in mentoring junior team members and outcomes.

  • Handling team conflicts or disagreements in data methodologies with examples.

Tip: Share concise stories that show initiative, leadership, and collaboration. Structured storytelling leaves a strong impression.
