Technical Behavioral

My interview with Lonza was a letdown because it felt really impersonal and disorganized. It kicked off with an AI screening, which lacked a human touch and made me feel like I wasn't really valued. What was even more disappointing was the lack of follow-up from the recruiter after talking to a person. They laid out clear timelines for feedback and next steps, but they didn't stick to them. I was told I'd get updates, and I followed up myself after not hearing back within the promised time, but still, no communication. This lack of openness and responsibility created needless worry and made the whole candidate experience look bad. At the very least, Lonza recruitment should honor their commitments and just send an email to let candidates know what's happening, considering the time and effort we put into applying.

The interview process was a bit lengthy. It started with several online screening interviews. The communications suggested these required preparation, but they turned out to be repetitive 5-10 minute meetings where they just told you they were putting you forward to the hiring manager. On the plus side, they did give an idea of what to prepare for the in-person interview. The actual interview was alright; they asked me to go through my CV and then asked some follow-up questions. After that, there were a few more standard competency and motivation-based questions, and it finished with a very basic maths test. They also included a lab tour.

First interview: standard questions, salary, availability to work in shifts, etc. Second interview: a few technical questions, chromatography steps, what is something interesting about you that is not on your cv...

Behavioral Technical

The interview process was quite slow. First, I had an interview with HR for usual questions about experience, relocation, and salary. The second interview was with talent acquisition, and they asked the exact same questions as HR, which felt like just a way to make me wait another week. The third interview was with the hiring manager and a team member, and this was the real one with technical questions about practical topics like how to handle projects, priorities, risks, and balancing priorities. Each interview was at least a week apart, so it felt quite long.

Confirmed questions2 questions
  • How do you manage when you have two priorities that conflict?
  • How do you balance two competing priorities?
