Salzgitter interview questions

After phone and 1:1 nterview process was told by sales dorecptpr and senior HR contact that an offer letter was in process and they were waiti g for CFO to return from Germany. One week later after I followed up, I was told sales was restructuring but my position was not in question amd asked to wait 2 more weeks. Afyer 2 weeks, I was then asked to come meet someone else Inwould be working with. All interviews presented very through questions and what next steps were to be. Position described in details with possible challenges discussed as well. Was informed I would hear back no later that that Friday. End of day Friday I followed up as I had not heard anything. Monday, HR emailed woth very generic response of "we are moving forward worh other candidates" It was very disrespectful to waste a month of my life and my very important job search. Leading me on, not professional at all. I was very excited to contribute to the growth of KHS.
