The use of AI assistance (ChatGPT, etc.) or online resources (Google, Stack Overflow, etc.) are not allowed for Optiver's assessments. This assessment is an approximation of later interviews where you will be expected to solve problems in real time. If your assessment is flagged for plagiarism this may result in your application to Optiver being disqualified. Once you complete the test, a group of our senior engineers will review the results and we will follow up within a week to let you know if you qualify for the next round. If you make it to the virtual final round, the interview includes a discussion of your code with one of our tech leads. Thanks again and good luck!
