Cruise Software Engineering Manager interview questions

Had a phone call with the recruiter, talked about multiple roles ate Cruise. She was able to identify a team for me and setup an initial phone screen with the hiring manager focused on managerial and behavioral questions. I moved on to the second round a technical coding phone screen with a Staff Engineer. He couldn't explain what the problem is and the expected output. I asked him several times about the input and output. I finally talked about how I am going to solve the problem, but he didn't have any feedback for me whether I was in the right direction. Looks like he already made up his mind about my candidature. I finished the coding but the output was not what he expected. Being a manager myself, I have helped mana candidates guide them in the right direction when they are stuck at some point. Totally disappointed with how the interview went. Ignored all other reviews here on Glassdoor and still took a call.
