To upload files to Talent from your computer, simply click the blue 'Upload' button on the right-side of the navigation bar from anywhere on the platform.
You can upload one or more files from each source listed on the popup screen (e.g., My Device, Dropbox, Google Drive, OneDrive, Box). You can drag the files into the upload modal, or select them using the 'Select Files to Upload' button.
Once you have the desired files in the upload modal, click the blue 'Upload' button.
After the upload starts, you can close the upload by clicking the 'Close/Continue upload in background' button. Then you can continue to work on other things in Talent while your upload(s) completes.
