[1] I don't know what those are. There are two extremes here:
1. PhD level Maths is involved.
2. You require them to have experience in a specific product (anything from a Python library to a framework like HF)
If your requirements are closer to the first extreme, well sure, you're gonna have to wait for someone that has that.
If your requirements are closer to the second extreme, why not just take a candidate? If it takes 2 months to skill up on whatever product you need them to skill up on, right now you would have had that position filled for the last 4 months with your ideal candidate.
And you haven't had a single candidate that could possibly pick up the missing skills[1]?
