however, thanks for bringing this up, based on what I have read in the descriptions of these enrichments, I think 'Find Tech Stack' might be the most suitable one since according to their description
"Looks at a company's historical job descriptions and aggregates all of the technologies that have been mentioned in those job openings."
Expect some margin of error though, I would expect false positives (eg, some companies like to list out a lot of tech stack they usually don't end up using or very marginally)
This is true. Companies like to mention general tools when recruiting. Like for accounting roles, they will mention all of Xero, QBO, Sage, Wave, etc even when they use just 1 or none of these to prequalify candidates with experience with tools.
