Hiring Pipeline & Robin — AI Pre-Screening for R Squared AI

A complete Google Sheets and Apps Script hiring pipeline built for R Squared AI's frontend developer hiring, with an AI agent called Robin that stack-ranks resumes A/B/C against weighted criteria.

Before

Inbound resumes piling up, no consistent way to evaluate.

Frontend hiring at R Squared AI was generating inbound applications faster than the team could evaluate them with consistency. Resumes lived in Gusto. Status updates lived in someone's head. Decline emails were written one at a time. There was no shared scoreboard for who was where in the funnel and no shared lens for what made a strong candidate.

What was needed: a single tracker covering every stage from application to offer, a consistent evaluation lens applied before a human spent time, and automation to handle the mechanical parts (status updates, decline emails, date stamps) so people could focus on the interviews that mattered.

What we built

A 60-column tracker with an AI pre-screener at the top of the funnel.

Preisser Solutions built the full pipeline in Google Sheets with Apps Script automation. The master tracker is 60 columns wide and covers the entire hiring funnel — application intake, resume review, three interview rounds, references, and offer status. Apps Script handles automated decline emails (three stage-specific templates), status updates, and date-stamping on every state change.

Robin is the AI agent at the front of the pipeline. Robin reviews resumes in Gusto and stack-ranks candidates A, B, or C against weighted hiring criteria before a human ever looks. The combination of Robin and the tracker means the team spends time on the candidates most likely to move forward — not on triaging the full inbox.
