The available Instacart Software Engineer report points to a demanding, coding-heavy path. Expect the coding work to become harder as you progress. One candidate described an assessment that began simply but packed in substantial coding, with tasks increasing in difficulty. Their example involved building a changelog with an appropriate data structure; unit tests checked correctness, so practice implementing a complete solution and validating edge cases under time pressure.
The same report describes three hard LeetCode-style interviews with little guidance once an exercise began. Prepare to communicate your approach, select data structures deliberately, and continue independently rather than relying on prompts from an interviewer. It also names a system design round, characterized as more moderate, plus a behavioral conversation that included why the candidate wanted to join Instacart. Have a concise, specific motivation answer ready alongside your technical practice.

Real interview reports from people who went through the Instacart process.
I passed the online assessment and made it through the full interview loop for a senior software engineer role. The first coding round felt solid, and I walked out of the system design interview feeling confident. But the second coding round was where things got tricky.
I ran into an interviewer who didn't create much space for back-and-forth. When I made assumptions about the problem or tried to talk through my reasoning, I didn't get much feedback or discussion—I was essentially told to pick my own assumptions and keep moving. That lack of dialogue threw me off balance. I tried to stay engaged and explain my approach, but without clearer guidance or the ability to refine my thinking with the interviewer, I felt like I never fully demonstrated how I actually problem-solve. By the end, I was told they were moving forward with someone else.
When I followed up, they mentioned a one-year cooldown for the same position. I haven't found much public confirmation of whether that's a hard policy or how it applies to similar roles at the same level, but that's what I was told. Despite the rejection, I have a genuinely positive view of Instacart and the process overall. I feel like I can come back stronger, and I plan to interview again when I'm ready. The experience didn't feel like a bad culture fit or a company I'd want to avoid—just a round where the communication groove didn't click the way it needed to.
Prep tip from this candidate
In the second coding round, prioritize clear communication and ask for feedback on your assumptions early—don't assume silence means you're on the right track. If the interviewer isn't giving you much direction, proactively surface your thinking and ask clarifying questions to keep the conversation flowing.

Synthesized from candidate reports. Individual experiences may vary.
One candidate reports an initial coding assessment that started easier but became progressively harder, with a high volume of coding. Their changelog task required choosing an appropriate data structure, and unit tests evaluated correctness.
The candidate describes three hard LeetCode-style interviews. They report receiving little guidance after the exercise began, so candidates may benefit from practicing independent problem solving and explaining decisions clearly.
A system design round was reported and characterized as more average in difficulty than the coding interviews. The report does not identify a particular design prompt, so prepare broadly without assuming a fixed domain.
The reported behavioral portion included a question about why the candidate was applying to Instacart. Candidates should prepare a concise, genuine account of their motivation and relevant engineering interests.
