Recruiter screening and Hiring Manager screening. Pretty standard process and the questions were regarding your resume and job descriptions. Nothing special or surprising to be honest. The question of role fit always come up with a technical leadership posting.
While the questioning were standard, the responses were not. In this case, the lack of response was the case. You are the employer, be bold and just it is not a good fit instead of ghosting candidate. Most companies after a technical interview with the hiring manager would provide a standard, canned email saying so. Not Motional... unfortunately.
