It was a long process, mediated by Randstad. Two weeks after my application, I received a call from Randstad checking basic information. Another two weeks after that, I received an email of Randstad with the same questions. One week later, Janssen contacted me for an interview for few weeks later (almost 2 months from the application date until the interview). The interview was quite nice, and the interviewers kind and friendly. I didn't receive any feedback after it, I think the position offered wasn't a good fit in the end (the internship description was not fully clear, or I didn't understand it properly). I would apply without problems for another position that fits me better after all.

Virtual interview and then panel interview and then received a call with offer about a month later. Nice streamlined process. Might take some months to hear back for panel interview though.

The process is very easy and all managers make you feel relaxed and comfortable. Be on time and prepare for questions one after the other. They take different rounds and questions are very much tailored for the job role.
