I completely agree with Oyster's comments. No-shows have become a major concern and drain on energy and resources. The thread starter is a recruitment consultant, making the task more challenging, cumbersome, and in the end, disappointing, emotionally draining the person on big volume drive days.
HR colleagues have presented good suggestions, but they seem too good to be true. Making freshers and mid-career candidates turn up for interviews is like a gamble. Nevertheless, these suggestions are hit and miss, so there's no harm in trying; we don't have many options either.
My 2 Cents in Such Situations:
1) Get a basic Client HR interview done telephonically. Involve the candidate in the interview process by assuring selection in preliminary rounds over the phone itself.
2) Reach out to the candidate rather than expecting them to come to you. Grab your mobile and get your feet on the street. Work from a campus Katta, CCD, Barista, or MG Road. Contact your candidate on the move. Meet people on the street, surprise them with your charm and offer.
Sounds wacky? Well, that is what India is! Think out of the box!
I got tired and irritated with no-shows, so I challenged conventional sourcing methods. I struck a friendly rapport with the HR of the client, convinced her to interview my candidates over the phone. I took my cell phone and hit the malls in the city. I approached these young, enthusiastic individuals and convinced them for an interview (Abhi-ke-Abhi). I could assess their communication skills and other non-verbal aspects according to my client's requirements and coordinated a telephonic call with Client HR. Once these candidates were in the loop of interviews, they would turn up at the client or recruitment office for further rounds. If on some days I couldn't get hold of Client HR, I would simply call my colleague and get a mock interview done to get these average Joes in the loop.
As I gained success in better turnout and conversion ratios, I made more friends, more referrals, and more contacts. When a recruiter strikes a friendly rapport, candidates are honest about no-shows and offer acceptance. Many times, I have driven my candidates to the client location for interviews. Well, it's all about how passionate we are to meet our goals.
I have been grilled, cooked, toasted, and fried in ITes (BPO) recruitment! Duhh! It's the most challenging time of my career chart!
