If you send all of your slack communications to IngestAI, it would include possibly channels where you discuss interview feedback. That's what the parent poster is saying.
Edit: This whole thread is goofy. It is the equivalent as saying what if you published your entire internal emails online.
The way IngestAI works is it takes your knowledge base as the input (markdown, docs etc) and answers the queries asked by the user on these knowledge base. ur primary usecase has been to simply learn from public documentation of companies and help answer the queries within their Slack/Discord community.
