A poor interview review and defense for senior engineers will have a big impact. The senior engineer review is divided into two environments: document review and defense. The document review is very simple. As long as you meet the requirements for papers, awards, patents, books, etc., you can apply. There are also academic qualifications. As long as the applicant meets these basic conditions, he or she will pass the key review. In the defense session, the pass rate is generally around 70%. After the materials have been reviewed, the defense must be carefully prepared.
