Candidates describe a Singlestore Software Engineer interview that leans practical. One candidate reported four rounds. They started by navigating an existing codebase and adding two pieces of functionality. Next came LeetCode-style data structures questions on arrays and trees, including two-sum, three-sum, and inverting a tree. The third round was database-heavy and required a complex query, and the last was a managerial conversation about fit and communication. That candidate was not offered the role.
A different candidate reported a shorter sequence. It began with a 30-minute hiring manager call and a 60-minute machine coding round that involved a React form with validation and redirects. A 60-minute discussion on scheduling client requests to a server followed, using pseudocode and trade-offs rather than full production code. That candidate said the interviewers were supportive and guided the discussion. The rejection cited a wish for more experience, even though the candidate felt both tasks went well.
An internship-labeled report also mentioned adding functionality to a large codebase. It included finding duplicates in an array in O(n) time with O(1) memory. The candidate said the interviewer was most helpful when they talked through their reasoning.
A few themes overlap and are worth practicing. Get comfortable reading unfamiliar code and changing it safely. Rehearse core array and tree problems, and keep SQL sharp, since the database is central to Singlestore's product. Narrate your approach and ask clarifying questions. The reports come from only a few candidates, and their loops differed, so expect variation.

The interview process consisted of four rounds and felt fairly practical for a software engineering role. In the first round, I had to navigate an existing codebase and add two different pieces of functionality, so it tested whether I could understand unfamiliar code and make changes without a long ramp-up. The second round moved into LeetCode-style data structures questions, with arrays and trees as the main focus. The third round was database-heavy and required writing a complex query, which made sense for SingleStore because database fundamentals are central to the product. The final round was managerial and focused more on overall fit and communication. I did not receive an offer, but my takeaway is that candidates should be ready for a broad loop: codebase navigation, classic coding problems, SQL or database querying, and a manager conversation. The specific coding prompts I remember included two-sum, three-sum, and inverting a tree.

Synthesized from candidate reports. Individual experiences may vary.
One candidate reports starting with a roughly 30-minute hiring manager call. It covered their background, the team, and why they wanted to join Singlestore. Other reports do not describe an opening call, so the format may differ by team. Prepare a concise story about your experience and why you want to join Singlestore.
Candidates report hands-on work rather than only abstract puzzles. One was asked to navigate an existing codebase and add two pieces of functionality. Another built a React form with validation, redirects on success, and error messages in a 60-minute session. An internship-labeled report also mentions extending a large codebase. Practice reading unfamiliar code and making small, safe changes while explaining your choices.
One candidate reports LeetCode-style questions focused on arrays and trees, recalling two-sum, three-sum, and inverting a tree. An internship-labeled report describes finding duplicates in O(n) time with O(1) memory. Review these fundamentals and be ready to explain complexity. Interviewers may reward clear reasoning, and one candidate felt that asking clarifying questions mattered.
One candidate reports a database-heavy round that required writing a complex query. Another reports a 60-minute discussion on scheduling client requests to a server, using pseudocode and trade-off conversation instead of full code. These may vary by interviewer, but SQL fluency and concurrency trade-offs are reasonable preparation areas.
One candidate describes the final of four rounds as managerial, focused on overall fit and communication. It is a single report, so do not assume every loop ends this way. Prepare examples of past projects, collaboration, and how you reason through ambiguous problems. Ask questions about the team's priorities as well.
