So to be clear for a given position you get 100 to 1000 resumes, then interview how many of those before deciding on 1 person? I am curious what the funnel looks like.
It depends entirely on the size and quality of the candidate pool, but I'd say very roughly:
* Initial candidate screening reduces the pool by 85–95% (leaving 5–15% of the initial pool)
* Interview #1 reduces the pool further by 50–66% (leaving ~3–4% of the initial pool)
* Interview #2 reduces the pool further by another 66–75% (leaving ~1–2% of the initial pool)
* Final chat usually doesn't reduce the pool, but it's one last pass for additional signal
* We choose a single candidate of whoever remains
For a position with 400 applicants, it could look like
* Initial screening leaves 40 candidates for interview #1
* Interview #1 leaves 15 candidates for interview #2
* Interview #2 leaves 4 candidates for final chat
* We pick from those final 4
