It took around 3 months for the whole process from Application to Rejection. The interviews was fairly simple, the first interview was to discuss the CV and basics, second interview was competency based with a short test based on hiring clients for a research panel. The interview ended with a tour of all Boots labs. The overall process was okay, I just had an objection with the time they took to just simply say no to me in the end. After the second interview they told me to wait until next week for a reply but I had to wait for 3 weeks to finally get a reply after i sent an email to the manager.
