Applied via the debut app, which sent me to the AI application page, fairly harmless application process, just add CV and personal details. Afterwards, get a link to a video interview page where you record some standard interview questions and answer a couple of technical questions, nothing too challenging just to get an understanding of where's you're at. Following this, we got invited to an assessment center which, for a first experience seems intimidating but when I attended was really friendly, they had a standup intro where you have a chance to speak to some of the current staff. This was really easy going, everyone's in the same boat as you so it was nice just to chat to some of the other applicants and a member of current staff about the company and working life. During the process we had a group presentation, a one to one interview and a one to one presentation on a technical subject, nothing you have to pre prepare so don't worry it's nothing you're expected to be an expert on! They interviewers were always really friendly and helpful, encouraging and I never felt uncomfortable during it.
