C3 AI Software Engineer interview questions

Received the HR call - attended the first interview (easy string question) - attended second interview (graph question) - attended third interview (heap question). The interview process was fast and everyone was very responsive and considerate.

The most confusing interview process I've had. - The recruiting team reached out, I wanted to learn more about the positions. They insisted me to send the resume with details on education, for my bachelor and masters (what degree/which school/when/etc.) .... keep in mind I was in school 9+ years ago! - No talk with hiring manager at at all, straight to semi-onsite interview .... 3 sessions scheduled, 45 min each - They asked me to study the company and product to show my interests during the interview - No idea which of these 3 interviews were supposed to be coding Vs architecture ... but that's fine - First 2 interviews done (I'm definitely not satisfied with how I wrote the code) - I joined the last interview, and then instead of interview, the recruiting team comes in and say they think I'm not a good fit, which on it's own is fine, but this is definitely not how I would describe the smoothest process - They also told me that I could "apply again" if I want to. Not the best interview process you can imagine for sure, and not the way to create in company.
