Google hangouts coding challenge. Answered the question correctly but they said emailed me a couple days later saying they didn't want to continue with the process. Question seemed incredibly impractical and interviewer made several mistakes while assessing.

Almost everyone I interviewed with at Simon Data was very friendly and encouraging. The first part of the interview was an online coding challenge. It was pretty easy and short. Based on that I was scheduled for an onsite interview that consisted of meeting with three different team members, two senior and one that was in the position I was applying for. One of the interviews involved much more product specific questions than I suspected. I did not continue on in the process after this onsite but was told the next steps would be phone interviews with more senior employees.
