C3 AI Solution Engineer interview questions

The first step was an online coding assessment, consisting of two coding exercises and a couple of questions on time complexity and data structures. After passing the screening, there is a live coding session. The final stage was a low-level system design interview.

I had an interview process that started with a hiring manager and then proceeded to a virtual onsite. The second round was scheduled for two, but keep in mind that if you don't have a solution for the first problem, they won't move forward with the next round. It’s a bit discouraging because at this stage, it feels like there's no real need for interviews—just send an exam with pass or fail criteria. The way you approach the problem doesn't seem to matter as much as having a working solution. If you can’t solve a dynamic programming problem in 40 minutes, it’s a dealbreaker. For this company, I’d recommend focusing on medium-level DP problems.
