Key point
Ask narrowly
A good feedback request does not say, “Please review my profile.” It says what you are trying to show, which sections to check, and what kind of reply will help you.
People are more likely to answer when the ask takes less than 3 minutes.
Who to ask
Ask people who can judge the part you are improving. A senior can check whether your projects look credible. A teammate can check whether your role is clear. An alumnus can check whether your profile matches internship expectations.
