The process for this role was very interesting and unique. First, after the normal online application, I was invited to an online interview. Next, it was a technical telephone interview. The assessment center was the last stage. Here's a detailed breakthrough of each stage: - Online interview : This interview was very simple and natural. Questions asked were similar to the following: Why BT? Why this role? What is your motivation? And questions similar. No technical knowledge is required. You just need to answer honestly and naturally. - Technical Telephone interview: This interview was very intensive in terms of knowledge required. You are given 7 topics and asked to pick two, where you'll be interviewed about technical terms, and technical knowledge regarding these topics. - Assessment center: This stage was the one I preferred. It was by far the most original and unique assessment center I've attended. 5 different stages exist in the assessment center. * A group discussion: You are given a topic to discuss with your group. You are tested on teamwork, and how well you perform in a group. Tips for this is being natural, not interrupting people, and being open to others' opinions. * 1 on 1 Interview: This interview is very similar to the online interview but in person. You are asked to talk about a time when you... (eg. worked in a team, communicated efficiently ... ) * Technical exercise: During the assessment center, at one point, you are required to do a technical test. In my area, this was a task that consisted in understanding code, and writing an algorithm. *Micro test: This is a 15-minute test, that is very interesting. It is not technical, and you are tested on your ability to communicate instructions and to explain a topic you've been handed. *Finally, the best part, a VR (Virtual Reality) exercise: You are lead to a VR room, where they will explain how to use the VR system. You are then required to perform multiple tasks, that are very interesting, and fun (Don't consider it a game though, because you are assessed.) To conclude, overall, despite the few challenges faced during this process, it is a very unique, original, and instructive process. You get to learn a lot about yourself. Tips: - Research BT as a company, its values, and its atmosphere - Know why you want to work in your field, and what makes you stand out from other candidates. - Don't stress, they are all very nice people that are trying to help you not make you more stressed. - No matter the outcome, learn from previous mistakes ( Ps. I got plenty of rejections beforehand, so don't let rejections bring you down, it is normal)
