Here is an idea on how to overcome the current harsh trust crisis. I mean, even having the best-in-the-world proposal for a prospect, there is a huge chance not to pass the initial wall of suspiciousness maybe 100% of decision-makers are having.
The idea is simple and quite obvious: to target linear employees of the department that benefits the most of your offer.
First of all, search for 2nd-level profiles within a company. The best approach is people from your homeland who approve connection requests much more often.
After the approval is got, briefly disclose the core of your offer to make it clear within 3 seconds of reading. Then ask for introduction to the required person.
It seems that it works in the best way with hiring candidates if the company has it's staff ref bonus program.
