Dexcom Product Manager interview questions

It’s been over a month since I gave my Hiring Manager interview and I’ve not had any updates. I reached our multiple times and the recruiter got back to me telling me they’ll keep me posted if they want to move forward in the process, however, at this point I’ve considered that I’ve been ghosted. What is even the point of making candidates wait if you’re not interested in moving them forward, just send the rejection and be done with it. Read a few comments about them being ghosters and trust me all of it is true.
