After I did a case study for them, they invited me to the interview. However, during the interview, the interviewers seemed really uninterested to host the interview (although they said they are satisfied about my case study). And one of the interviewers looked around and did not really care about what I was saying, nor gave me any feedback regarding the cast study. The whole process only took 10 mins which I deem they obviously have no interests to interview me, but if the interviewers have no interests to host this interview, please just be honest instead of wasting a lot of time from applicants.
