The Amazon Future Engineer Scholarship is a highly competitive scholarship, yet it is not a win that is out of reach. Every year, Amazon picks a few hundreds of students (roughly 200-500 depending on each region and year), while thousands of applicants globally attend their call.
Despite the fact that Amazon doesn't disclose an official acceptance rate, some speculations believe it is around 5-10%, which means that it is more selective than most local scholarships but less so than elite programs.
Besides financial need, leadership, and interest in computer science, academic record is the major factor among other elements in the selection process. So, well-rounded and highly prepared applicants indeed can qualify.
Therefore, it is indeed a big challenge but a carefully crafted application can get you your scholarship award.
