For the take home assignment they give you a badly formatted csv dataset with 100k rows and ~30 columns with transactions from Wise users with quite a few data quality issues such as missing values, nonsensical ones etc They ask you to do an analysis to identify transactions related to financial fraud and provide multiple ways to do that, suggest mitigation strategies once you identified them and then evaluate the impact to the affected users as well as the monetary impact to the business. This ridiculous exercise suppossedly needs 2-3 hours max and no previous experience with fincrime. In reality it needs quite some familiarity with different types of financial crime and at least a few days to do the analysis and write the report. Just because I liked the exercise I actually spent this time and reported 3 different ways to identify fraudulent transactions suggested a complete framework to tackle the affected users and pulled external public data with reasonable assumptions to make a business case for the impact. I received a rejection because the depth of the analysis wasn't adequate. I honestly don't know what was the expectation from this take home challenge. It's a complete and utter waste of time. I cannot begin to express how ridiculous this was.
