Wasn't the second part of the question pointing out the max consumption date for each data center?
Thanks for reaching out!
In the interview, Tina tackles the question regarding the total energy consumption on each date across all centers. She begins by calculating the total energy used on each date, then applies a filter to identify the date(s) with the highest consumption. Her approach involves grouping the data by date to sum up the daily consumption, followed by identifying the maximum value among these totals. Around the 10-minute mark in the video, she demonstrates the code for calculating total consumption and proceeds to filter out the date with the maximum usage. By strategically reordering her steps, Tina actually simplifies the problem-solving process, making it more efficient and straightforward.
Hope this helps.
