Interview Process
The interview consisted of a series of questions administered through HackerRank. The first part included basic multiple choice questions that assessed general data science knowledge and simple probability. This was followed by coding questions. The first coding question involved working with a pandas DataFrame. The second question required training a Convolutional Neural Network (CNN) using PyTorch. Candidates were given 50 minutes for this section, with additional time from earlier questions available for use. A Jupyter Notebook was provided to process the dataset, and candidates needed to upload their results at the end, which were scored based on accuracy.
