I recently successfully secured an interview for a 2026 software engineer position at Databricks. I started by digging deep into Databricks’ culture and technology, and made sure my resume and LinkedIn showed real results. I also reached out to current employees and joined tech events. Of course, the most important thing is that I practiced coding challenges and focused on expressing myself clearly.
However, I have to admit that hard work alone isn’t enough for me to land an interview for a Databricks software engineer position. I also need to master some lesser-known techniques. To be honest, I used a real-time AI interview assistant to help me figure out part of my answers.
I am really grateful to Linkjob AI for helping me pass my interview, which is why I’m sharing my entire Databricks software engineer interview experience here. Having an undetectable AI interview tool during the process indeed provided me with a significant edge.

Landing a Software Engineer role at Databricks was a challenging but rewarding experience. From the recruiter call to the onsite interviews, each stage tested my skills and preparation, especially the questions from Databricks coding interview. Here‘s a breakdown of how the entire process went.
The first stage was a Recruiter Call. This was mainly an introductory conversation where I talked about my background, experience, and why I was interested in the role at Databricks. The recruiter also gave me an overview of the interview process, including timelines and expectations. It was a low-pressure call, but I did my best to convey my enthusiasm for the role and how my experience aligned with what Databricks was looking for.
The Technical Phone Screen was the next stage and it lasted about an hour. I was interviewed using CoderPad, where I had to write working code in real time. Here’s how it went:
I was given a 2D grid and had to find the shortest time and cost from a starting point S to a destination D. The grid contained different transport modes, each with a different time and cost multiplier.
The challenge was to run BFS (Breadth-First Search) once for each mode and calculate the total time and cost, then select the best mode.
The interviewer asked me to optimize the solution and avoid scanning the grid multiple times. I implemented BFS using a queue and tracked visited nodes.
This question tested my ability to optimize algorithms and handle edge cases.
I was also asked to implement a function that would uniformly sample edges to add between disconnected graphs so that they would become connected. The trick was to ensure the edges were selected uniformly from all possible solutions.
This involved using union-find (disjoint-set) to track connected components and carefully selecting edges without bias.
The interviewer guided me through the process and asked about the complexities of the solution.

The next stage was a Hiring Manager Call, where I spoke with the manager for an hour. This call was more focused on my background, problem-solving approach, and alignment with Databricks culture. We also discussed:
My past projects and how I would apply that experience to the Databricks environment.
Behavioral questions focused on teamwork, problem-solving, and handling conflict in engineering teams.
This call gave me a deeper understanding of the role and how Databricks operates.
The Onsite Interviews were intense and lasted about 4-5 hours, spread across multiple rounds. Here’s a breakdown of the rounds:
I was given a tree structure representing a file system with directories and files.
I had to recursively count how many files were encrypted and unencrypted.
Then, I was asked to implement a function to encrypt all unencrypted files. The catch was optimizing the time it took to encrypt files, given different constraints.
This round tested my understanding of recursive algorithms and optimization.
Next, I worked on a problem involving a set that supported creating snapshot iterators.
I had to implement an iterator that would give a snapshot of the current set, but adding/removing elements in the set should not affect existing iterators.
The interviewer asked me to optimize the space complexity of the solution, especially when dealing with multiple snapshots.
This problem required me to think about versioning and how to handle incremental changes efficiently.



This was one of the most challenging rounds. I had to implement a thread-safe LRU cache with a TTL (Time to Live) mechanism.
The interviewer asked me to handle concurrent access and ensure thread-safety while performing eviction based on the TTL.
We discussed locking strategies and how to ensure the cache could scale under high load.
This round tested my knowledge of multithreading, caching strategies, and race condition handling.
In the System Design round, I was asked to design a distributed rate limiter using a sliding window approach.
We discussed how to scale the system to handle millions of requests per second while ensuring fairness across clients.
I also had to consider fault tolerance, network latency, and how to handle request bursts.
This round tested my system design skills and my ability to think about scalability in distributed systems.
