Elsevier interview questions

I had an interview with a recruiter over the phone and an interview with an executive via Teams. I thought I was interviewing with the hiring manager but during the interview I learned that they were in the process of hiring the hiring manager. The person interviewing seemed like she was distracted and going through the motions but not very interested. I followed up with a thank you email. The recruiter told me they would send my email to the interviewer. I was surprised that after the interview there was no follow up at all from the recruiter - not even a generic email. When I checked on the status online a month later it still showed the application was in process but I never heard back from anyone. It seems like applicants who get to the stage where they are interviewing with an executive on the team should at least receive a follow up email informing the applicant that the role was filled.
