Of course I would -- it's hard to find people. Some companies give referral bonuses to incent their employees to recruit on their behalf. If the idea is to get "inside information", I think it will fail (or at least, hope it will). Not treating company information as secret (especially to strangers) is a sign of a dysfunctional organization.

If it's just "feel" that you are looking for -- then I think you'll get that.

Yes, it's just feel. A peppy intelligent response will give me a more positive feel than no response or a cold, guarded response.

That is far from a good indicator, but it is a start.

And if the communication goes well, I can schedule a call or continue the email correspondence.
