The 31.9 percent lift suggests that verbal discussions can effectively resolve misunderstandings or technical disagreements that might otherwise lead to a final rejection. For applications in Tech Center 4100, leveraging this lift can significantly improve the odds of success beyond the 56.6 percent baseline. Practitioners should prioritize interviews to address complex rejections.
