A standard process with 4 to 5 interviews from HR to engineering, sales, and CTO.
The issue with C3 AI is the company's lack of empathy for its applicants.
Communication is unclear and unprecise, deadlines to provide a formal answer are not respected, and HR prefers to ghost you instead of giving the correct information. No matter your own priorities or constraints.
Despite a positive outcome and an unofficial offer, C3 prefers to make you wait three months, saying "the validation process is long" instead of saying they are not recruiting anymore. They keep you dreaming, hoping you will pause your life for 6 months until they choose the right time to send you the contract.
