I interviewed at American Express (Londres, Inglaterra)
Interview
This was one of the best interview processes I have ever experienced. Although it was quite extensive, every stage was well-structured and communicated clearly from start to finish. From the initial HR screening to the final interview, the entire process felt transparent, organized, and candidate-focused.
What stood out the most was the level of support provided throughout the journey. For the first time, I experienced dedicated interview preparation sessions before the actual interviews, which helped me understand the expectations and feel more confident. The HR team was absolutely amazing—responsive, supportive, and genuinely invested in ensuring a positive candidate experience.
Even though the process was long, the consistent communication, professionalism, and thoughtful preparation made it feel worthwhile. It set a high standard for what a great recruitment experience should look like.
