Databricks Mock Interview
Practice real databricks DSA coding problems with an AI interviewer
The Databricks Interview Process
Databricks's interview process evaluates your expertise in distributed systems, data engineering, and algorithmic problem-solving. It starts with a phone screen where you solve 1-2 coding problems in 45 minutes. If you pass, you move to the onsite which consists of 4 rounds: 2 coding rounds, 1 system design round, and 1 behavioral round.
Databricks emphasizes distributed systems and data engineering fundamentals. DSA problems range from medium to hard with a focus on data structures relevant to large-scale data processing. System design rounds focus on building data lakes, streaming platforms, distributed computing frameworks, and analytics engines.
The difficulty level at Databricks is medium to hard. Mid-level candidates face medium problems with distributed systems follow-ups, while senior candidates tackle hard-level problems. Knowledge of Spark internals, Delta Lake, and data engineering patterns is highly valued. Clear communication about trade-offs in distributed systems is essential.
What You'll Practice
DSA Problems
Medium to hard problems with emphasis on data structures relevant to data engineering, such as trees, graphs, and DP.
Distributed Systems
Practice designing data pipelines, distributed computing frameworks, and fault-tolerant systems at scale.
Data Engineering
Design ETL pipelines, real-time streaming systems, and data lake architectures using Spark and Delta Lake.
System Design
Design data platforms, analytics engines, and large-scale processing systems at Databricks scale.

Why Databricks Interviews Are Different
Spark & Delta Lake Knowledge
Databricks uniquely values understanding of Apache Spark internals, Delta Lake, and the lakehouse architecture. While not required, familiarity with distributed data processing frameworks significantly boosts your candidacy.
Data Engineering-Heavy System Design
System design rounds focus on data-intensive systems: ETL pipelines, real-time streaming, data lake architectures, and distributed computing. Show that you understand batch vs. stream processing, fault tolerance, and data partitioning strategies.
Research-Oriented Mindset
Databricks values engineers who think deeply about problems and can discuss trade-offs at a technical level. They appreciate candidates who understand the theory behind distributed systems, such as consensus, partitioning, replication, and consistency models.
