I applied through university. I interviewed at C3 AI (Santa Barbara, CA) in Oct 2018
Interview
Started with a behavioral, going over resume. Next was a coding challenge, which was done on hackerrank. This was 2-3 coding questions, equivalent to 1 leetcode easy and 1-2 leetcode mediums. Then was the final interview, in person with 2 technical questions.
Interview questions [1]
Question 1
General behavioral questions, a lot of resume questions
Got the OA it was very straightforward DFS solution but towards the end it had a certain factor that was confusing. They showed some C++ code even though my preferred language was Python which sort of threw me off.
I applied online. The process took 3 months. I interviewed at C3 AI (United, PA) in Feb 2023
Interview
I forgot if there was an OA or not, but there are 2 rounds of technical interviews. The interviewers were both nice and helpful. Overall, it was an OK experience.
