Residency selection is the process by which medical students apply and are matched to a residency program in their desired specialty after completing medical school. This process involves submitting applications, attending interviews, and ultimately being matched to a program through a national matching system. Residency selection is a critical step in a physician's training and determines where they will receive their postgraduate education and training in their chosen specialty. The competitiveness of residency programs varies by specialty and can be influenced by factors such as academic performance, letters of recommendation, and clinical experience.
