Tableau Software Software Engineer Core Server interview questions

One Phone Screen, A few coding questions for homework, in-house interview. 4 hrs of technical questions. Engineers seemed very happy to be there. Yes it's gone public but it's clearly in the sweet phase of a software company. Rapid growth, happy customers etc. Only bad part of the experience was getting a rejection via voicemail from the recruiter. Would have been nice to hear in person after the time and preparation investment. She didn't respond to me after leaving the voicemail.
