    I applied online. The process took 5 daysinterviewed at Zillow in November 2014.

    Interview Details

    They sent me one coding challenge consisting of two questions one is to implement insert and delete for tri-nary search tree, other one is to convert string to integer. They just asked me to send code in a file, they don't use Hacker rank or any such tools. I did both and tested it well, but i got a rejection mail after three days. I have read similar experiences.

    Application Details

    I applied online. The process took a weekinterviewed at Zillow in September 2014.

    Interview Details

    Applied online via their website. Was contacted shortly after and asked to complete 2 coding challenges. They were the same other people mentioned here. Convert a string to a long and implement insert and delete on a trinary tree. I have near 10 years of experience and know quite well how to do things such as this. Still, I took my time and spent about 4 hours making sure all of the code was write. I wrote plenty of unit tests to ensure it would all work and added comments all over as to be sure my intent in the code. After making sure the code was working perfectly, I submitted it to the HR person. A few days later and I find out that they decided to pass on me due to my answers to the coding challenges. I'm not quite sure what it is Zillow is looking for exactly. It boggles my my mind that they would pass on me this early on without even speaking to me any further or asking for more challenging puzzles to solve. The hiring process here is some of the worst I have seen. It would be nice to have a little feedback about what it is exactly they are looking for. I wanna agree with the other reviewer on here that more than likely they are using some kind of random guess or lottery pick to choose who gets to move on or not. I was not pleased with how this all turned out. In light of that, I do not recommend at all!

    Interview Questions
    • None, these were both easy questions to answer. I would have loved to opportunity to have tried something more challenging, then at least I would understand why they turned me down, but not for the ones they asked me.   Answer Question

    Interview Details

    Initial HR Screen,
    Coding Test

    Submitted the answers to their coding test after spending about a day. They rejected even for the initial phone interview right after the coding test. Not sure what went wrong in the coding test or what is their expectation. Whatever it may, set the right expectation for the coding test so that people don't waste their time

    I applied online. The process took 2 daysinterviewed at Zillow in June 2014.

    Interview Details

    Applied online and got a call form a technical recruiter. I was then given a coding exercise to complete at home and send. The questions were pretty simple as mentioned in some other person here - string to long, insert & delete in trinary tree. I completed the exercise along with JUnit test cases covering all possible scenarios I could think of and returned it early morning the next day. After a day I received an email saying they would not be moving forward with me. When I asked for feedback I was told it was based on my coding exercise. I am surprised with this since my code was working and did what the requirements asked, was well tested and documented(in my opinion). The only conclusion I can draw is, they were doing some sort of lottery to pick candidates for the next round of interviews ;-)

    Application Details

    I applied through a recruiter. The process took 1+ weekinterviewed at Zillow in May 2014.

    Interview Details

    Referred by recruiter and given what seems like standard questions from the other posts on here. Very long turn around and getting final decision.

    1. String to long conversion
    2. Trinary (trenary) tree insert and delete

    I spent about 3-4 hours getting problems coded up, documented, and tested. Solid rejection with no explanation other than my code wasn't good enough. Let's set things straight, I have 10+ years of experience, my code was well documented and had full java doc comments. I had accompanying unit tests to verify functionality and even made the trenary tree problem with generics. The only thing that could have possibly been done better is making the tree auto balancing, but given that most at home coding challenges are 30-60 minutes I felt like I already expanded enough effort.

    Whoever is reviewing the coding solutions has an UNUSUALLY UNREALISTIC BAR.

    Application Details

    I applied through an employee referral. The process took 5 daysinterviewed at Zillow in April 2014.

    Interview Details

    The first call with a recruiter was followed immediately by their standard take-home coding exercises: insert/delete from a ternary tree (which they call a tri-nary tree) and converting a string into a long. Straightforward questions. I decided to include not only a solution but also unit tests, and in such a way that I would expect to pass a code review for check-in. This isn't my first dev job. While the code functioned, and as far as I know was production-quality, I received an email about one day after I submitted the response that they were not going to ask me in for a screening. Disappointing, as I have no idea what they were looking for that I didn't do. I heard this complaint from other reviewers, but I assumed that they just solved the problem the fastest way -- I thought for sure having tests, comment blocks, and code structured for use in an application would impress enough for an interview.

    Interview Questions
    • Questions weren't difficult, but obviously I wasn't able to provide something they were looking for (and not asking for).   Answer Question
