You can still apply if you don't match all the requirements!
When an agency creates a job they may request that you have certain skills to do the job. The app will show you which requirements these are and which ones you are missing. NB: You can still apply if you don't match all the requirements!
If you need to update the agency on which skills you have, go to "Profile" > "Skills" and select the ones you have. Try to make a habit of updating your skills each time you gain a new one!
