You must first log out of the previous candidate account you registered and tested.
Go to your candidate's login URL.
Replace "mycompany" with the company name you registered in your Vervoe account.
If you are logged into a candidate account you will see the account dashboard. Click on the profile icon on the top right corner of the account and click log out.
You will then be able to test as a new candidate and should not receive a 404 error.
** You can also just open your test invite email using a different browser or an incognito browser in Chrome or Firefox or clear your browser cache before trying to test the experience again.
