Rivian Engineering Manager interview questions

Step 1: Recruiter call Step 2: Hiring Manager call Step 3: Virtual onsite In the virtual onsite, they cut short the interview because I didn't fare well. They did not inform me about the cancellation of other rounds and I had to wait for 2 hours on the call thinking that somebody would show up. Finally, a recruiter called and apologized saying that I didn't do well in the first round. The feedback that I got that I did not answer them in detail, but they have not asked me to explain more on a particular instance of the topic.

I applied online for a manager position, in addition to being referred by several employees. During the initial screening the recruiter asked me why I picked that particular position and not the engineering position in that same team. I answered that I'm meeting or exceeding all the requirements in the job description for the manager, so I decided to apply for that position. He proceeded to tell me that this job might not be available anymore, because there might be an internal candidate being promoted into the role shortly, my role would be more of a lead position, but the hiring manager would know more. I proceeded to the hiring manager interview and asked about the situation when given the opportunity to ask questions. The hiring manager explained that I would start as an individual contributor, because he doesn't put external hires into manager positions. He'd rather see who from the team is the best candidate for the position and then promote that person into the manager role. I understand the reasoning, but then why would you post the manager position at all? This appears to be a bait and switch tactic, and apparently I'm not the only one who has had that experience (see review from late March this year).
