My story: nontarget undergrad, nontarget MBA, Big 4 auditor for a few years, recently moved to the transaction advisory division of a mid-tier accounting & professional services firm (think McGladrey, Grant Thornton, BDO) in a mid-size city (think Minneapolis, Cleveland, St. Louis). To be a bit more specific, my work is primarily financial due diligence for private equity firms and corporate development divisions. I'm happy to answer any questions about the value of public accounting, the transition to transaction advisory, differences between audit and transaction advisory, exit ops from audit or transaction advisory, different accounting firms and sizes, the nature of transaction advisory work, how transaction advisory people view those in IB or PE, or anything else in the accounting and M&A realm.
I cannot comment on any matters concerning craft brews, crocheting technique, renaissance fairs, Tinder, and equine husbandry. Pretty much anything else is fair game.
A caveat: my move to transaction advisory has been relatively recent, and I want to acknowledge that my level of expertise is accordingly low. I think a transaction advisory AMA will be useful due to the relative lack of abundance of information on WSO, but if anyone has corrections or anything to add to my responses, please feel free to contradict my perspective - I won't be offended. Advice-seekers should also calibrate accordingly.
