Curai interview questions

I applied online. The process consisted of 6 interviews. Not sure why but had to do two interview rounds with the hiring manager. The only positive is the engineers on the panel seemed bright and motivated. After the final round, completely ghosted. I know the job market is in favor of employers, but out of the 5 companies that I went through the final stage, this was the only company that ghosted me with 0 feedback after finishing the last round. I don't recommend wasting your time to be honest.
