2. Enlarge the photo at the same scale (different scales will deform the face), so that one of the length and width sides of the photo is equal to the rectangular frame, and the other is less than or equal to the rectangular frame.
3. Assume that the width is equal, but the photo length is less than the length of the rectangular box. Then put the photo into the photo frame, and the gap between the top and bottom (that is, the distance from the photo to the top and bottom of the photo frame) should be equal. It's best to have a photo of your resume on a white background, so that you can see your head clearly when you print it.
4. Don't beautify the photos on your resume to be too different from my real face. Otherwise, the interview will be poor or leave a bad impression on HR. ..
