If you want to appoint the same tags to multiple applicants, you can add the tags in bulk. To appoint the same tags to many applicants, you need to go to the Talent Pool and select the applicants you wish to appoint tags to. On the menu that will appear at the bottom of the screen, click on the three dots and then Add tags.

To add tags, you can either type the tags you desire to add, or you can select from the list which consist of the tags added from Settings. If you type a tag that is not on the list, then you should click on Create or press Enter.

After typing your desired tags, click on Assign Tags and you will see that the tags will be appointed to the applicant.
