In addition to valid points made by KB and (Cite Contribution), the following steps may also be helpful to make a selected candidate join.
1) Commutation.: - In Mumbai,apart from distance, the way one has to commute to his/her work place also weighs on the minds of the prospective candidates in making a choice. For example a candidate from Belapur in will prefer to go for a Job at CST than for one at Lower Parel, since, for Lower Parel, he has to get down at Kurla and then catch a train to Dadar and then change over to Western Railway and then catch another local for Lower Parel and the ordeal may not end there, he/she may have to walk down or take a cab to his place of work.This is not to speak of the harrowing experience of getting into locals at Dadr and Kural in the evening rush hour while returning home.Though you may find a good candidate loacted at a place which is not connected to your place of work straight, the chances of his accepting your offer will be dim. he may go for ajob with lesser pay, if he can commute easily to his workplace. If the candiadte is a woman , she will be doubly concerned with this aspect.
2) Secondly, while sending mail for interview, you can mention that the candiadtes who are interested joining the job on their selection, despite their location, need only appear for interview.
