Dear Professional, after almost 10 years of experience in Big4 audit firms I decided to share my knowledge with you, together with some colleagues of mine. I worked in different Big4 audit firm performing audit of international companies in the manufacturing, holding and finance sector in different countries as US, UK, Netherland and Italy. The content created has an operative approach, with detailed guidance step-by-step, to let people learn on the spot how to perform audit procedures (for auditor) and understand how an audit is performed (for everyone else). The courses are in english and guided by the founder of HAW - How Audit Work that is an organization that provide audit related services, including teaching.
