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. The process took 3 weeksinterviewed at Palantir Technologies in January 2015.

    Interview Details

    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 in January 2015.

    Interview Details

    Applied online. Contacted by recruiter to attempt 1.5 hr online coding challenge on HackerRank. Finished it and passed most of the test cases provided. Contacted 2 weeks later for a phone interview. Asked me a questions about finding duplicates in an array and then incrementally modified it to make the problem more difficult by finding duplicates in an index range and in a value range. Solved them with some hesitation but went ok overall.

    Recruiter scheduled me for a second interview for the next week with another engineer. This time the entire interview was dedicated to coding - no chit chat. Asked a question about parenthesis matching and finding the minimum number of edits to balance parentheses. This was harder since there was no clear algorithm to approach this but just some general intuition to what constituted an unbalanced string. Solved it with some hints from the interviewer giving examples where my solution so far wouldn't work and so on. It took me longer than I would have liked. Also was expected to actually produce working code which scanned input and printed out statements since HackerRank lets you run the code in-browser.

    Was promptly rejected. Not surprised. They have somewhat difficult interviews. Google was harder conceptually, but Palantir cared more about details. I was also never clear as to what position I was applying for. There are several engineering intern roles - full stack, backend, front end, FDE, etc.

    Gave coding challenge online after sending in application. This was a 90 minute timed question on interview street. It was pretty challenging, practice beforehand. They give a sample test option say that you can get your bearings.

    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.
