Mercedes-Benz Research & Development North America Project Manager interview questions

Three interviews over three months: 15 min HR screening, 30 min phone, and a one hour in-person. Phone interview with position manager and teammate. In-person interview with department lead, position manager, and teammate. No feedback or any responses to follow up emails, just a surprise “next step” every three weeks. MBRDNA requested a 20 minute presentation on Wednesday night before the Monday morning in-person interview. 5 min “about you”, 15 min case study of what you would do in the role. This seemed ok for this industry, could be a deterrent for others. Four HR people throughout the process. 1) Sr. Recruiter reached out for screening and arranged the team phone interview. 2) Associate that arranged the in-person and travel. 3) Associate that met with me at the front desk. 4) Associate that walked me to the in-person interview room. Three and a half weeks after the in-person interview I received a one sentence email denial from the Sr Recruiter. No response to a request for feedback. MBRDNA paid for a round trip flight and covered rideshare expenses to/from the airport. My suggestion to MBRDNA would be to provide the bare minimum level of feedback to candidates. ~26 hours went into this process with nothing to show for it and no indication of what went wrong.
