Primer AI Machine Learning Engineer interview questions

Probably the worst interview experience of my life. Home assignment way too time consuming. For the onsite, they didn't seem to expect me and there was a general sense of confusion. I waited 15+ min for the second interviewer and I have the impression that they pulled a random guy that had no idea was supposed to interview me. Finally I was supposed to meet the CEO to show me the product, but after waiting another 15+ min they told me that 'something came up' and they will get in touch. In general a lot of time wasted. 2/10 will not recommend
