Cosmogence interview questions

Horrible experience. I had a 30 minutes introductory interview, the interviewer has show up with 15 minutes delay visibly upset, she did not apologized for the delay. The interview was an annoyance for her since the beginning. She was rude and aggressive, speaking a terrible english. She was speaking so fast that I could not undestrand her. When I asked her to slow the peace and repeat she got mad!! She started yelling every single word!!! 30 minutes after the interview they sent me an email saying they were not taking me for further consideration and retry after 6 months after enanching my skills. HOW COULD THEY KNOW ABOUT MY SKILLS WITHOUT A TECHNICAL ASSESSMENT??? An horrible experience.
