Talking to people who want you to hire them is going to introduce a lot of bias with respect to responsibilities and expectations at their current company.

No one is going to tell you: “They say senior engineers are supposed to lead large scale cutting edge projects from beginning to end but really I’ve just been working on a login page for the past 3 months.”

Do you regularly hire the seniors you talk to as principals? Really a better question is do you hire juniors from that company who are ready to be promoted to senior there as principals at your company?
