Starling Infrastructure Engineer interview questions

After applying for an infra role at engine by starling, the recruiter got back to me quickly, set up an initial call with him, then an introductory technical chat with a team member which I passed, then I was a assigned a technical challenge which I submitted for their review, but I was ghosted. I never heard back from them since I submitted my test, no matter how hard I followed up, my emails have constantly been ignored. So maybe dodged a bullet!
