Thank you for taking the time to share your feedback. Regarding your comment about ‘obsession’, it is true that we are passionate about scaling our Intelligence gathering to enable our customers to manage risk and investigate crime. We value your time and aim to minimise the impact of the 'take home assignment' stage for candidates. Our technical screener is designed to be straightforward with an option to explain what you would do with more time. These decisions often lead to interesting discussions later in the process. The task asked for the ‘address hash’ to be passed into the script as an argument. Whilst the approach of setting the address as an environmental variable technically works, it is not as simple to test different addresses by changing the address on the command line. Thanks again for your honest feedback!
