HR practises remain more or less the same, across industries.
Whether you have auto factory or steel factory PF rules are same,ESIC rules are same for workers.
Knowledge of process by HR makes him more knowledgeable about the whole environment of work,beyond that HR practises cannot be markedly different.
That is what i understood from your answer is it correct? And please advise what should be answered if this question asked in an interview ?(Change of industry)
First of all you should state that you are not looking for change in the Industry but for better career opportunity to work as an HR professional in any industry where you are allowed freedom and authority to apply your knowledge at a level it deserves.
The basic elements of HR job remain the same in any industry ie Recruitment, Compensation management, performance management, employee relations and developing sound HR policies etc.
The role of HR whether in Automobile, IT, Chemical , Engineering or service provides different challenges and that is why familiarity with those challenges is what creates industry bias in the minds of recruiters in selecting HR person. But any HR professional having sound knowledge and well rounded experience can add value to the function in any Industry.
