I recently interviewed with Mastercard and went through a rough situation. I had four interview rounds, each lasting about an hour. Interviews can naturally be nerve-wracking, and I experienced quite a bit of anxiety during each round. After the fourth round, I was informed that I wasn’t selected almost after 3 weeks. However, a week later I was contacted again and told that, due to mixed feedback, they wanted me to attend an additional one-hour interview. After completing that round, I was told my feedback was positive. Yet, two weeks later, I unexpectedly received an automated email stating that the position had already been filled, with no feedback or explanation provided. It made me reflect on whether it was truly worth spending over two months in the interview process, only to end up with this kind of response in the end.
