The recruiter head hunted me through LinkedIn. They gave me a one and a half hour test on Hackerrank. The test was pretty difficult but was doable in 90 minutes.

    I applied online and after a few weeks was asked to complete a programming challenge online. I found the challenge to be quite difficult and was unable to get a working solution within the time allotted. There was no phone interview prior to or after the programming challenge, and I was not offered a position.

    I applied online. The process took 4 weeksinterviewed at Palantir Technologies.

    Interview Details

    Applied online and was provided a coding challenge a few weeks later. Coding challenge was difficult, but doable within the allotted time. After the code challenge was a technical interview with one of their software engineers. Right from the get go, the interviewer wanted to really know if you knew your stuff. The interviewer asked questions on algorithms, questioned methodology on past projects, and just tested the rigor of everything I said. Next was the online coding portion of the phone interview which was probably one of the hardest interviews I had done, partially because I had forgotten a lot about linked lists. Had an idea of how to do it, but couldn't finish it in time.

    Approached at a career fair, received a online code screen. The website was tough to use, took me awhile to figure out how to submit my code and develop in the online environment. In hindsight, I should've prepared beforehand to sit down and focus.

    I applied online. The process took 2 weeksinterviewed at Palantir Technologies in September 2014.

    Interview Details

    Applied on company website. Received an email next day inviting me to take an online coding challenge on Hacker Rank. Did the challenge (answered it perfectly) and was contacted by HR to schedule a phone interview. Interview consisted of the same question with progressively more difficult variants. This was done using a collaborative coding tool (also Hacker Rank) where I had to implement my solutions. At the end, the interviewer asked if I had any questions.

    Interview Questions
    • Given an unsorted list of integers, return true if the list contains any duplicates and false if it does not contain any duplicates. You do not have to identify the duplicate value.   View Answer
    • Given an unsorted list of integers, return true if the list contains any duplicates within k indices of each element. Do it faster than O(n^2).   View Answer
    • Given an unsorted list of integers, return true if the list contains any fuzzy duplicates within k indices of each element. A fuzzy duplicate is another integer within d of the original integer. Example: If d=4, then 6 is a fuzzy duplicate of 3 but 8 is not. Do it faster than O(n^2).   View Answers (2)
