STAT (Saudi Arabia) interview questions

They asked me for an interview on spot which went quite well on my part. They then told me they’d send me a test on xyz date even though I was applying for an internship or an entry level position. They never sent it and I had to send a follow up email. They delayed it again and I had to email them again. After they finally sent the test and I sent it back to them, they never responded nor even acknowledged which was very unprofessional of them. I sent a lot of follow up emails but never got a response until I called them and the person on the line told me that they will discuss it with me tomorrow. When I called again, he simply gave me a 6 word answer saying I will send you an email. He sent me the same generic rejection email with no explanation. Waste of time honestly.
