what are the backstage activities of the HR after they find a candidate most suitable for the position advertised, which takes them time to revert ?

Hi Sanjay, There are various activities that are involved in the final selection/offer of a candidate:1.
HR Selection2.
Business Team Selection based on their availability and Geographical Presence.3.
Reference Checks4.
Background Checks5.
Medical Test6.
Verifying the candidate's current salary.7.
Estimating an Offer to be rolled on the basis of the Candidate's existing salary, the Organizations's current Salary Structure and Range.8.
Making an Offer.
All the above take some time, although the HR team tries to complete the same within specified timelines.

Thanks Amal for your answer and support !:) Responding to you little late as I am new to bayt forums and was wondering whether one can only use the board to write answers or one can also pay appreciations to professional people showing guidance.
Appreciate your effort for the same.
