audit cash, send bank confirmation, trade payables, receivables,interco, loan, expense and sometimes revenue section if it is not too complicated

A2 must lead small engagement from start to finish.they will also audit more sensitive sections like payroll and more complicated sections like tax and rou assets and liabilities

Senior will do consol and those complex stuff which require more professional judgement

That was during my time lah. but now all the seniors quit liao so A1 do S1 work? lol
