Dear Tammaraykoli ,
It's sometime challenging as well as opportunistic too , when you work alone in any of the department . So when we seek to care the work nicely and timely , we must need to work smartly .
So as per your requirement , first you need to prepare the manpower list as the no of person desired in various departments in the coming time , as it won't be perfect but atleast an idea will be ok with you .
Your next task should be the type of hirings required frequent or on urgent basis as per the need of your organization or your observation , you can get the list of that from your management too , if you are new to organization or department .
Now as you have got a rough idea of the type of requirement , you need to prepare the Job description of each roles and levels . This will help you in easy posting of the jobs . If you have prepared it in advance , then with slight changes as per the situation , you can work easily in posting the jobs .
Now once you are done with this task , keep the JDs ready in a folder as per the roles . So you need to be smart in managing the data .
Now once you are done with this , you need to search the sources through you will be posting the job or getting the resumes .
Sources of posting jobs can be on walls, notice board, employee referrals,, media, newspaper, online free sites are many ( but post on relevant sites which should be active in your areas or field of business operation of your business) .
If your organization is willing you can outsource your hiring too or hire a third party for this but it must be the resort when you are not able to manage the workload and organization is well willing for this but do care your work pressure too as am not sure of the other task you are handling at present .
now when it comes to handling the interviews, line up of candidates , you can take help of office staffs to manage the applicants but with the permission of your management .
Looking over the number of applicants and your work schedule , do call them as per your time availability and if there is the burden or bulk recruitment , you will surely have to tell your management for extra support either in-house or through agencies , consultants .
you will have to check the number of rounds to be conducted as per the requirements too .
I hope this may help you a bit if not too much in getting your concern task handled well .
have a nice day .
Regards
