ABB Material Planner interview questions

I had a total of 3 interviews: 30 mins HR Teams interview, 1 hr manager and sr planner Teams interview and 2 hrs on-site interview with the managers. Overall, the interview questions were simple and straightforward. However, when I went for the on-site interview, the manager was kept mentioning this job will be challenging for me, and I was wondering why did you invite me here if you think I'm not qualified for the job? It has been 2 months since my last interview, and I heard nothing from them. After I took my PTO for all these interviews, they just ghosted me without even saying thank you. I would not recommend this company or the Warminster site because this shows a lot of the company or the organization.
