It may be because the resume file name filled in by the online application contains special characters (such as/\: *? "<& gt|), which makes it impossible for Deloitte to save your files. It is recommended that you change the file name, use pure English or numbers to name it, and ensure that there are no special characters in the file name to save it smoothly. If the problem still exists, I suggest you contact Deloitte website customer service for help.
