Interviews - When leaving blank on initial job entry, it should not make a POST request

[nosvalds]

Describe the bug When going through adding a job, the final step is to add interview notes (if you've had one). The form says you can leave it blank if you haven't. However if you do leave it blank the client still makes a POST request to the interviews route and recieves a 422 error.

To Reproduce Steps to reproduce the behavior:

1. Login
2. Add Job
3. Fill out info on first 2 forms
4. Leave interviews form blank and click finish + save
5. Look at Dev Tools

Expected behavior I would expect the client not to make the POST request if the interview form is left blank by the user
