I can't open a resume. Is it better to print two copies or the front and back (one)? What does HR usually do in an interview?
Better make one. After all kinds of simplification, it can be reduced to one. Just give a general description of the contents in your resume. If the interviewer is interested, he will ask questions. We can expand it then. The feeling of two pages is complicated. It really takes two pages to be double-sided. It is awkward to put the two together, and it is not convenient for the unit to collect and sort them out.
