Hi Antony,
No, the processes are not the same across the company except perhaps for the 3. Gratuity and Payment. It is similar in all the companies as it is governed by the law.
As for 1. Recruitment, different companies utilize different means of sourcing candidates. At the same time, companies have different interviewing techniques and levels. Some recruit from the campus, while others prefer centralized campus. Some prefer walk-ins, while others prefer consultants. There are lots of ways that a company handles its recruitment, and most of the time the company utilizes more than one method of recruitment for its requirements.
2. Training and Development depend on the training requirements of each individual company and department. So, it cannot be the same for all departments, let alone the companies.
As for how can we simplify the complexities in these processes, it needs to be done individually for each process and problem.
Thank you.
