HOH Water Technology interview questions

I applied through their website. A recruiter contacted me within a couple days. I had one interview with the recruiter asking a bunch of behavior questions looking for insights on my personality. I then had an interview with the HR manager with similar questions. I was told any final interview would be with the hiring manager. I was then ghosted, with two emails to the recruiter being ignored. In this day an age, a basic "we are moving forward with other candidates" is easy and professional enough to do as opposed to ghosting someone!
