Atlassian|Python Data Engineer Interview preparation|Detect Frequent Badge Entries
This Python function sifts through employee badge data to identify individuals who have entered a room three or more times within any one-hour window. It begins by organizing entry times for each employee and then checks for one-hour periods with three or more badge-ins. The function outputs a dictionary with each employee's name as a key and the earliest set of entry times as values, ensuring only the first instance is recorded if multiple instances occur.
