For the basics, start with the [overview](https://tandem.joveo.com/support/interviews/overview.md).

## Screening and AI interviews

### Can I change the questions after a role is live?

Yes. Open `Hiring flow`, expand the stage, click `Edit stage` and then `Save changes`. Changes apply to candidates who reach the stage afterward.

### Which languages can I use?

Screening runs in English. Each AI interview stage runs in one language: English, Spanish, French or Hindi. To ask for another, choose `Request a language` in `Edit stage`.

### Do candidates need a camera?

Only if you turn on `Camera` for the AI interview stage.

### Does Tandem reject candidates?

No. Candidates who don't meet your bar wait in Needs review, and only you move a candidate to `Rejected`.

## Invites and credits

### A candidate's invite expired. What happens?

They show in Needs review as `Invite expired`, and the expired link tells them to contact you for a new one. Credits reserved for that invite are released after 7 days unused.

### Why is a candidate "Waiting for credits"?

Your balance ran out, so AI interviews and other actions that use credits are paused. Roles, candidates, scheduling and Tandem's chat keep working. [Buy credits](https://tandem.joveo.com/support/billing/buy-credits.md) to carry on.

### When are AI interview credits spent?

Tandem reserves them when it sends the invite and spends them only when the interview happens.

## Reports

### Why does a candidate show "Couldn't be scored"?

Tandem didn't have enough information to score them. Open their profile and read what they did answer before you decide.

### Can I download a recording?

Yes. In the candidate's `Reports` tab, `Recording & Transcripts` lets you download the recording and the transcript.

## Scheduling

### Candidates can't book an interview. What should I check?

Check that Google Calendar is connected and that your availability is saved, in `Calendar` → `Availability`.

### Can I use Outlook or iCloud?

No. Calendar works with Google Calendar only.

### Do interview guests need a Tandem account?

No. Guests are added as attendees and get the invite by email.
