DraftKings Business Data Analyst interview questions

After applying, i heard back almost instantly with an invitation for a first round interview (next day i think). However, it took almost 2 weeks between being invited to interview and actually having a time scheduled. The first round was a phone screen from the recruiter. I was blown off during the first scheduled appointment and was only rescheduled after I directly reached out and set up a new time. When that call did eventually happen, it was a complete waste of time. It literally took 2 minutes despite telling me it would be a "45 minute discussion." After this I was quickly moved forward into a phone call with a member of the analytics team, where we went through a quantitative case interview. This went smoothly, and I moved on to round 3 where i spoke with another analytics team member on the phone for a more open ended business case, which also went smoothly. I was then invited in to the office for a final round interview consisting of two more cases and a behavioral interview. After leaving the interview I was told I would either receive an offer or a rejection as soon as that same day, but no later than the end of the week. It is now 3 weeks out and counting, and i have heard nothing one way or the other despite multiple follow up emails. TL;DR: Every interaction with the HR department, whether it be phone screens, scheduling the next round, or hearing back about the previous round was absolutely terrible. However, the analytics team and the people you meet in the office are fantastic. The issue does not seem to be a DraftKings-wide problem, but rather an incompetent/indifferent HR department.
