Workflow

How Quollo works, end to end.

One platform across the whole loop — from designing the plan, to running the call, to deciding with confidence.

01
Before the interview

Design the plan once, reuse forever.

Turn fuzzy hiring intent into a structured interview your whole team can run consistently.

  • Build interview flows from questions and briefing notes, grouped into sections.
  • Pick a rating type per question: 5-star, thumbs up/down, or no rating.
  • Attach materials — images, briefs, or code snippets — that surface during the call.
  • Co-create with the AI assistant: drafts sections, suggests follow-ups, adapts to seniority, domain, and language.
  • Schedule via Google Calendar, Outlook, or your ATS — or create interviews through the public API.
