Mammoth Biosciences interview questions

I was contacted by the Hiring Manager. We had a great conversation roughly an hour. I followed up about next steps & I was told they went ahead with other candidates as I did not meet their business needs.

Applied through a referal. HR recruiter contacted and interviewed over a phone call. Hiring manager interview occurred over a face-to-face virtual call. Got invited for a virtual interview. 45 min presentation and 7 or 8 one-on-one meetings. HR did not meet. HR recruiter sent an email for feedback immediately after the interview. As promised they sent me a rejection email after a week. The email was very generic and had no clear reason for the rejection. Upon asking for a feedback. I received no response.
