Big 4 internal audit advisory, is it the same like working in internal audit units in specific companies (as per your experience what is your opinion?

i think it depends upon one's experience . if one is working in top4 audit companies but his experience is limited for example to risk management or internal control or whatever while another auditor working in any auditing firm he will get training in all fields of auditing, but i think training in4 top companies is prestigious    

Big4 internal audit Advisory means to have internship with top4 Auditing Firms in any country
