Do not interview at Zillow! They treat their candidates horribly. See below:

The process started with a phone interview. The interview was challenging but not overly so. I was told that I did very well on it and was brought in for a full onsite.

The onsite consisted of four one-hour technical interviews, one lunch, a manager interview, and a final session with the recruiter. All together, it was over six hours.

During the interviews, I felt that I was doing well and, for the most part, received positive signals from the interviewers. This was true for all except one interviewer with whom I had a communication gap and could not understand what they wanted.

I received a rejection call several days later. I was very surprised and asked the recruiter to provide feedback. The recruiter promised to call but never did. Only after I reached out again did he send a templated email stating their policy was not to share feedback.

I learned later through an indirect but reliable source that only one interviewer gave me negative feedback, and this led to my rejection.

• A company that rejects someone based on one interview after keeping them onsite for six straight hours does not value candidates.
• To make things worse, the recruiter's ignored communication and subsequent failure to provide any feedback demonstrates Zillow's general attitude toward candidates.

I will never interview with Zillow again and suggest anyone who values their time not bother with them. I am a senior engineer and have interviewed at many companies. Even at those where I did not succeed, I felt that my time was valued. Zillow does not. They waste your entire day and then reject you based on a single fault without providing any reasons.

A company that treats its candidates this way will eventually treat its employees the same. From my perspective, I am very happy that I did not end up there.

A simple binary tree related question.
