The possible causes for candidates not joining a company can be many, but I wish to share a few that come to my mind.
Impression During the Interview
The impression that a company creates at the time of conducting the interview is crucial. Fearing a poor show of candidates, many companies slot several candidates at the same time. This leaves candidates waiting for a very long time. During this agonizing wait, in some companies, none of them bother to offer water, let alone refreshments. The embarrassment they face in checking the location of a restroom, etc., creates a poor impression of the company.
The solution to this problem is to spend time speaking to the candidate to check their interest, willingness, and convenient time to attend the interview. Then, send an email seeking their confirmation to attend the interview at the scheduled time slot. Follow up for their confirmation, and speak to them the day before on the pretext of guiding them to your company (only to find out whether they are likely to turn up for the interview). If they are an outstation candidate, you can check if any assistance is needed for their accommodation. Once they arrive, allocate a separate logbook for them to enter their name and contact details at the Security office. This log is useful to analyze the number of candidates called vs. the number of candidates who have attended and the quality of candidates shortlisted, and the source of recruitment, whether it is job portals, newspaper ads, references, or consultants. This information is useful in choosing the right source for the respective position at a later date. Advise a seasoned security person to guide them to the waiting room where HR greets them, offers refreshments, and checks if they wish to use the restroom facility. The candidate is then advised to fill up the application blank and guided on how to fill up the form (the sequence of presenting educational qualifications/experience/the policy of indicating references, not friends or relatives, etc.). If there is a likelihood of a delay, the candidate has to be informed, and if needed, lunch is arranged. Reimbursement of expenses, if applicable, is done.
Thereafter, communicate to the candidate the status of the interview. In case you are unlikely to select them, you may write stating that their profile does not match your current requirement and that you will revert as and when a vacancy suiting their profile arises in the organization. This is because you may find them not suited for the position you are looking for, but a vacancy may arise that matches their skill sets at a later date.
If you do not find them unemployable, you can politely inform them of the skills they lack, and this feedback is given to improve their skills in future interviews. Generally, when we give such feedback, I have observed that candidates take it in the right perspective.
Offer Letter and CTC Negotiation
You can give an offer letter to the candidate, obtain their concurrence on the CTC worksheet, and then hand over the offer letter alone without the CTC. This is to ensure that the offer letter is not used as a bargaining tool by the candidate with the current employer. The entire offer of appointment is handed over at the time of their joining.
We find that some HR professionals tend to push the candidates too hard to accept the salary structure offered by them, and the candidate accepts the offer momentarily. But sooner or later after joining, they start the job hunt again. In some cases, as the employer has a choice, candidates also have a choice, and they select the employer who offers a higher CTC. But I will certainly not subscribe to the view of offering a substantially higher pay package to the prospective candidate by upsetting the current wage structure that exists in the organization. Such a move could bring in discontent amongst existing employees.
Handling Unsolicited Applications
Even when you do not have a vacancy, you may find candidates walking in/sending in profiles to your organization. Do not discourage/trash them. Instead, review these and call them for a discussion if you find the profile interesting. If you find them good, you can inform the candidate that you do not have a vacancy right now, but they will get a call when a vacancy suiting their profile arises in the organization at a later date. By this way, you have created an impression that you have not turned out the candidate when they approached you, and they are more likely to join when you call them when a vacancy matching their profile arises in the organization.
Though there are many other finer aspects like these, I have shared a few of them.
