Applied online which required a Dropbox account. Was contacted by email to schedule a phone interview. They use a single email address for all communication seemingly to shield unwanted contact. Once it was scheduled, I was emailed a spreadsheet of a sample set of ticket IDs, unix epoch times, and two letter country codes (which over half were blank). I wrote a script to convert the times and country codes to a human readable format, then organized the data to show number of tickets for every country on every day within the sample set. Created an Excel spreadsheet and made charts to visualize the data and then made a one page summary of my analysis. During the phone interview, it was made apparent to me that the interviewer did not review my spreadsheet and went only by my summary. I recapped my summary trying to give an estimation of how to organize their team with such poor data. It was very uncomfortable to make any recommendation as there's no indication of how their team is run. Interviewer seemed to stick to a well-rehearsed script, even when an introduction about themself. A day later, I was told they were not moving forward. BTW the source data and 'detailed' analysis is on github. Save your time and just use that, because they obviously don't value your time.
