I applied online. The process took 3 weeks. I interviewed at C3 AI in May 2021
Interview
The interview process was long (I had seven interviews over the course of a few weeks), but the questions asked were not very difficult. I am a new grad, and the interview questions may be harder for experienced engineers coming from industry.
Interview questions [1]
Question 1
Questions were about data structures and algorithms. Think Leetcode easy to medium level difficulty.
I applied online. I interviewed at C3 AI (Redwood City, CA)
Interview
In the screening interview, the engineer taking the interview was really rude. He started flaming my Uni out of random, indicating that most of the graduates were from "Stanford/Berkeley", then started to flame my experiences. I don't think, I was asked one question which was relevant to my experience or the role.
I applied online. I interviewed at C3 AI (Chicago, IL) in Nov 2025
Interview
The process was pretty standard. I received a Hackerrank OA followed by a hiring manager round. Another leetcode style and system design round followed by a final behavioural round. All the feedback was positive but after the last round, the manager called me and said they were going in a different direction and said he twasn't allowed to give any feedback.
It was long and had many stages. Phone interview then technical then behavioral again at the end. Know both design and algorithmic problem solving. Overall felt decently challenged but still possible.
