Lonza Project Manager interview questions

I had a call from HR and then they booked me for my 1st interview with the hiring manager. after that, they asked me to prepare a presentation for the next stage interview and then never heard back from them.

The first interview was scheduled after about 2 weeks from online application. Then 3 interview rounds followed (1 HR, 2 business). The interviews were well structured, with case study, I had a chance to get to know potential manager as well as team members. After the 3 rounds of interviews there was no further information from the company. I sent an email, I also tried to reach HR contact person by phone - no reply... about 1.5 months after the last interview I got the information that I was not successful. Despite very interesting, insightful interviews, lack of communication and missing respect to the candidate made the experience rather negative. Hope the team will improve.
