C3 AI Data Science interview questions

First contact was with recruiter email. The interview with one of existing employee (not hiring manager) to discuss position, my experience,etc. second part of interview was a 5 page white paper on use cases for AI given my industry knowledge (prefer not to specify). You are given 7 calendar days and a few links for guidance. I submitted it and never heard back. I followed up with the recruiter three times and finally received a “come back to us in a few months” email. No feedback or any other type of communication. I felt the purpose of the job postings was to get prospects to write white papers which can then be actually used by employees as an idea generator. For someone who spent many hours on it and be sent a generic email is really disappointing. If I had gotten feedback or a 30 minute convo with hiring manager, my feelings would’ve been different. Honestly very disappointed in how they treat people. Do not spend time with white paper unless you actually talk to hiring manager and believe it’s a real job posting.
