Hi kmmohamedishmail,
The post recruitment activities may differ from company to company, post recruitment is all about the joining procedures that fall after the selection process, usually how it happens like the selected canditate may ask to come and join in a particular date that mutually agreed by them and certificate verification will be thr that the select canditates should submit their photo copies of their documents after this induction(orientation) will be given to the canditates like familiarizing the culture of the company so that the new employee may feel free,then the training period will start to them normally for 1-6months, after that actual job will start to them, Hope i cleared ur questions,
cheers,
