Allen Institute Data Scientist interview questions

1 recruiter phone screening, 1 HR interview, 1 onsite with presentation and 1-on-1 with dozen other team members. After the onsite, they ghosted me for months. I've tried to follow up with emails every week, and the recruiter just acted like they didn't see it, even though they promised to get back to me "next week" both in person and in email. Felt super disrespected for my time, consider all the candidates have spent lots of time preparing for their onsite presentation.
