Pergunta de entrevista da empresa Tokopedia

1st user interview: what you would do when given noisy data (what preprocessing steps you would carry out), variance, covariance, correlation, recall, precision, F1-score, examples of when you need precision over recall and vice versa, what do you know about A/B test (what steps you should do), and some study cases. 2nd user interview: mainly at a higher level than in the previous interview. He also asked me if I had an experience where I wrote a custom loss function (could be from a paper) of a deep learning model.
