Arcadis interview questions

Quick process from application to initial HR interview and then to second interview with the hiring team. Interview was relatively straight forward. But then post second interview, Arcadis completely ghosted me (over 6 weeks no response). Despite follow up, I heard nothing back. Poor form from a company that I would expect better of. I understand many applications across the industry receive no replies, but to do that to someone who has done 2 interviews is just rude.
