Had a guy reach out to me - he's looking at recruiting jobs, and asked for some advice. Here was my off the cuff thoughts.
First - check out the archives from StlRecruiting.com, specifically 2005-2006. I talked a lot about staffing because that was my job at the time.
Second - Focus on your metrics.
1) Look at as many resumes as you can and keep count
2) Interview as many people as you can on the phone and keep count (never let a call go longer than 30 minutes
3) Interview as many people as you can in person. (never let it go over 30 minutes).
4) Make it a practice to make 100 phone calls a day.
There is no substitute for pattern recognition in this business. Get it in early, and you'll understand recruiting faster than your peers. Being smart doesn't help. It's about repetition.
Third - Buy a mirror and put it on your desk. As the phone rings, smile at it. An old secret but a good one.
Fourth - if is your plan to stay in this business, you have to proudly identify yourself as a recruiter and a salesperson. There are no extra points for being a good recruiter in a sea of bad ones. Understand your job is to make introductions, and try not to take it personally when clients and candidates lie to you. Over time, your successes will outweigh your failures. Never apologize for being a recruiter, and never apologize for other recruiters. That will suck the life out of you, and you'll start looking for exits.
