I utilized balanced class accuracy to handle the skew in class labels and explained the AUC curve during the follow-up. In the coding round, I approached the multi-part question methodically, ensuring I covered all parts and emphasized writing comprehensive test cases.

Onsite Round

Questions:

Candidate's Approach

In the coding round, I ensured to address each part of the question thoroughly and focused on writing robust test cases. During the bug squash round, I quickly identified both bugs, fixed one, but faced challenges with the second. I utilized available resources like API documentation to assist in my debugging process. For the ML design round, I aimed to outline my thought process but struggled due to interruptions. In the manager chat, I discussed my experiences but noted the need for more concrete metrics regarding project impacts.
