Akira Technologies interview questions

A recruiter initially contacted me and scheduled an informal/getting-to-know-you interview with HR. After talking to HR, she scheduled a call with the Hiring manager and Me. The hiring manager mostly asked scenario/how-to questions and seemed to rush me off in the end. I followed up to check on the status and it was radio silence. It's pretty rude to just ghost people after having them take out time out of their schedule to interview with you.
