Aisera AI Engineer interview questions

One of the worst experiences ever. Introductory call and home assignment. After devoting time of building a good solution to the assignment, there were 4 more calls and noone checked my solution. One interviewer also asked questions in a rude way who didn't see my assignment. A complete waste of time and as one interviewer told me you have to negotiate about having more than 15 days off annually. After 1.5 month noone answered for decline or offer. Don't waste your time and respect your CV and experience.
