Recruiters on LinkedIn are of a different kind. Most of their message are not worth your time and are better ignored outright. Occasionally I get a message for an opportunity that seems too good to be true, but, what the heck let’s see where it goes anyway.
Apparently these recruiters aren’t familiar with the concept of custom email domains. When I was asked for an email address I was initially thrilled because I check LinkedIn very infrequently. I was glad we were moving to a method of communication I have an eye on.
Except we didn’t. The recruiter needed to verify my email address, of
which, sure, I gave up an address that was <recuriting company name>@jrgnsn.net. It’s good to keep tabs on who’s trying to sell your
information, which I didn’t believe this company was going to do…
until they questioned the email address.
Long story short, I missed the opportunity because the recruiter dragged his feet on emailing me. That’s fine, I don’t believe this was a legitimate opportunity anyway.
It seems that using Gmail automatically increases your chances of getting interviewed, which I want to be on the record as saying, I think that’s fucking stupid.

I don’t believe there are any valid security reasons for this. I think it would be very easy to see that the domain belongs to me with this blog hosted on it.
