Starship Technologies Robot Operator interview questions

First, there is an interview on the phone, they ask you about your previous job and experience, and they explain about Starship and ask you: would you like to work part-time or full time, and then they tell about paid per hour. Second, there is a case study, and after that, there is another interview. I was rejected in the case study step and after 6 months I applied again because when they rejected me they sent an email to me that it is possible for me to apply in the future, but when I applied for the second time, before having any interviews, they sent me an email that unfortunately we decided to not move forward because want to give a chance to new people and I was shocked why they say: "keep an eye on our jobs page "when they don't want to give a chance to people who were rejected before
