I received the OA 10 days after applying. It was a 3-hour, real-world problem.

First, I had to get data from the API they provided, which contained thousands of data points.

Then, I cleaned the data and designed a method to achieve the required goal.

Finally, I posted the answer to another endpoint.

If the answer was incorrect, they didn't specify the error, only suggesting I check my logic.

I successfully finished the OA in time, and HR sent an email congratulating me, stating that recruitment updates would be provided in 2 weeks. However, I received a refusal without a meeting or further information.

Online assessment about a real-world problem. Can code in any language.
