I applied online. The process took 2 weeks. I interviewed at C3 AI in Sep 2019
Interview
Received a hackerrank coding challenge, 1 easy and 1 hard graph problem. Correctly solved both challenges, but received a rejection stating "Score was not sufficient" Little do recruiters know - candidates can also see how they have fared on hackerrank. I passed all test cases for both problems, so this is BS. I followed up stating that I had a perfect score, but no reply. I was really interested in this company, I wished they would have given a proper explanation for rejection.
I applied through a recruiter. The process took 3 weeks. I interviewed at C3 AI
Interview
Not easy communication with recruiter, never replied any of the emails. Plus got rejected on the day of final interview. Final interview was already scheduled and got rejection email before few hours of final team matching round
Few behavioral questions and a leetcode easy / medium question for first few rounds. Very understanding interviewers. They were supportive and gave me ideas to answer the questions. It went very well.

I applied online. The process took 1 day. I interviewed at C3 AI (Redwood City, CA) in Dec 2024
Interview
Applied for a full-stack developer in Redwood City, CA, USA Dec 2024
1st- round went well, 30min behavioral (about my goal, strong and weak points)
2nd- round was given LeetCode Medium 279. Perfect Squares. I haven't prepared for dynamic programming tasks. I couldn't write a single line of code, but overall, I had a good experience.
After the first coding, the following interview must be another coding, and after System Design (if I pass the first one)
Hopefully it helped
