Roblox Principal Software Engineer interview questions

The recruiter I worked with Nate Leslie. He was polite in the phone calls but the follow-ups and conversations were very poor. Lot of thrashing in emails and correspondance. Long period of silence and sudden follow ups with fast requests to interview quickly. There were time that the onsite required me to be in the office and then that was changed. The director level interview was nothing like what the recruiter said it was. He was completely wrong. NO follow up after the interview when results were not good or any feedback or suggestions. I did close to 6-7 rounds of interviews. How about a 15 min phone call to tell me what happened and why Roblox did not go with me?
