Easy Positive London, England

After my CV got accepted, I was sent an online assessment on values-based scenarios. It was built around case studies where I had to work through what I’d do, including a ranking-style element, and it leaned heavily into Transport for London’s “green” and sustainability themes along with teamwork. I liked that the interface felt guided—there were resource tiles provided to help me answer the questions—and the whole thing was automated right after I submitted.

Even though it felt pretty approachable, I didn’t move forward. The process overall felt efficient and structured, but the assessment was definitely the gate I needed to clear rather than a conversation with the team.

Average Positive Hong Kong

My application flow was pretty straightforward and professional. I started with an initial online application and then did a competency-based video interview. After that, I was invited to a final assessment centre.

At the assessment centre, I had a group technical exercise alongside a one-on-one interview with a senior engineer. The individual discussion centered on my project experience and my technical knowledge, so it felt less like broad screening and more like a check on how I’d actually work through real problems. I appreciated that the final round felt concrete—there was a sense of technical relevance rather than generic questioning.
