Building an interview flow

Choose Linear or Branching mode, and route follow-up questions based on how someone answers.

The Interview Questions step of the wizard offers two modes, picked up front.

Linear vs Branching

  • Linear — a simple ordered list of questions, asked one after another.
  • Branching — a visual flow where an answer can route the conversation down different follow-up paths.
Warning

Switching from Branching back to Linear deletes every question and branch — a branching flow can't be flattened into a list, and this can't be undone. Switching from Linear to Branching is safe: you're offered a choice to carry your existing questions over as a starting chain, or begin empty.

Which questions can branch

Only three question types support a conditional: Yes/No, single-select Multiple Choice (not when "Allow Multiple Selections" is on), and Rating Scale. Short Text, Long Text, and Open Ended questions have no fixed set of answers to branch on, so they can't.

Adding a branch

On a branchable question, click Add conditional to attach a Conditional node beneath it. What happens next depends on the question type:

  • Yes/No — two branches are created automatically (Yes / No) and can't be edited.
  • Multiple Choice / Rating — you build your own branches with Add rule: pick one or more answer values to route down that branch (e.g. group a 1–2 rating into one branch and a 4–5 rating into another). A branch's rule can be changed later with its pencil icon, or removed with its X.

As long as some answer values aren't yet assigned to any rule, an automatic "Any other answer" catch-all branch stays visible, so no response falls through with nowhere to go.

Attaching questions to a branch

Each branch row has its own + button — click it to add the next question specifically down that path. Different branches can lead to entirely different follow-up questions, or rejoin later by both eventually reaching the same next question.

Editing a question that already has branches

If you change a branching question's type, or remove/rename options that a branch's rule depends on, Synthight warns you before saving — a type change drops the conditional (and everything below it) entirely, while removing an option only shrinks or deletes the specific branches that depended on it.

Deleting a conditional

Deleting a Conditional node asks you to confirm, then removes it and everything downstream of it — every question in every branch below that point. There's no way to delete just the branch point while keeping its children.

Reading the canvas

The flow isn't a free-form drag-and-drop canvas — nodes lay themselves out automatically as you build. Toggle between a top-to-bottom and left-to-right layout with the icons in the top-right corner, and the view auto-zooms to whichever node you're currently editing.

Frequently asked questions

What happens if I switch an Interview from Branching back to Linear?
It deletes every question and branch — a branching flow can't be flattened into a list, and this can't be undone.
Which question types can have branching logic?
Only Yes/No, single-select Multiple Choice (not when "Allow Multiple Selections" is on), and Rating Scale. Short Text, Long Text, and Open Ended questions can't branch since they have no fixed set of answers.
What happens if I delete a Conditional node?
It removes the conditional and everything downstream of it — every question in every branch below that point. There's no way to delete just the branch point while keeping its children.
What happens if I change the type of a question that already has branches?
Synthight warns you before saving — changing the type drops the conditional (and everything below it) entirely, while removing an option only shrinks or deletes the branches that depended on it.
