Kinisi interview questions

Had a 15-minute chat with the CEO who seemed very enthusiastic about my application. Then invited for a technical interview in which the interviewers went through off-topic questions as they thought I was applying to a different job, they actually asked me what job I had applied for at the end when I said it seemed off-topic, Next day my application was rejected saying I don't have enough experience. Bit of a mess really and a waste of time.
