In the end, only three candidates were shortlisted, and I wasn’t among them. However, the experience was incredibly enriching, and I cherished the opportunity to learn, grow, and connect with professionals in the tech world. The Meet Visa Event was a significant milestone in my journey, and I look forward to more exciting opportunities in the future.
