Real, anonymous reports from people who interviewed for Software Engineer at C3 AI, newest first and distilled into what to expect across the loop.
I went through a pretty defined sequence: a hiring manager screen with behavioral questions woven in, followed by two coding rounds and then a system design interview. The early technical parts were what I expected—DSA-style problems that felt fairly standard to work through—but the system design session was where things soured.
I started with a pretty light behavioral conversation that felt friendly and casual. The questions were the usual sort—why I wanted the company, and what my weaknesses looked like—and it set a relaxed tone.
The interview process typically starts with a recruiter call, followed by a technical assessment and multiple technical rounds, often culminating in a system design interview and behavioral discussions.

Technical interviews primarily involve coding questions, often centered around data structures and algorithms, with some candidates reporting a mix of coding and system design discussions. The difficulty level can vary, with some candidates finding the questions standard and others feeling they were pushed to their limits.
System design interviews are a common part of the process, but candidates reported mixed experiences, with some finding the discussions unstructured or overly focused on a single 'correct' solution rather than collaborative exploration of ideas. This aspect can significantly impact the overall impression of the interview experience.
Behavioral interviews often include STAR-style questions and focus on cultural fit and personal experiences, with candidates noting that these discussions can feel more subjective and less technical.

Many candidates expressed disappointment not just in the outcomes but also in the lack of constructive feedback following their interviews. This left them feeling uncertain about their performance and the company's decision-making process, especially when they felt they had performed well technically.
