    Interview Details

    Can't remember first interview, standard coding tests. Secondary interview was in office, with four people. Various questions asked, usually coding/algorithms. Pretty basic things, know the runtime of your algorithms, make sure everything is in smallest big O possible.

    Sample questions were: correct a series of code,
    Find the largest algorithmic progression
    Regular palindrome shenanigans
    Some coding question that was effectively "Merge Two Sorted lists"

    Interview Questions
    • Disjoint algorithmic progression: given a set of numbers in no given order, find the longest algorithmic progression, assuming you can skip items as you desire.   Answer Question

    I applied through college or university – interviewed at Palantir Technologies in February 2013.

    Interview Details

    About 1 month after dropping resume at career fair, got an email asking me to take an only coding assessment. A sample problem in their test environment is provided.
    Given a problem, code an answer in your language of choice in 100 minutes.
    It was pretty impersonal. Make sure you try the sample problem and get the I/O for that working before attempting the actual question.

    Interview Questions
    • The given question was a standard algorithms question, however, I had not been exposed to the material before so it was fairly confusing for me. Leave plenty of time to debug, and don't overthink your approach. There are time/memory limits, but getting the problem itself done in time is most important.   Answer Question

    I applied online. The process took a weekinterviewed at Palantir Technologies in February 2012.

    Interview Details

    I was asked a bunch of algorithm questions about algorithms. They asked me to solve three problems and for each one I had to give the run time of the algorithm. I took the interview before taking any algorithms class so I did my best to answer.

    I applied online – interviewed at Palantir Technologies.

    Interview Details

    I was asked by the HR to complete a coding test powered by InterviewStreet. It was not too hard and managed to solve the problem in the time limit.
    After this, I had a telephonic interview with a developer. It sounded like he was eating during the interview. I was a little shocked. But, the interview was fine. I was asked two coding questions which I had to write on Google Docs.

    Interview Questions
    • It was a weird kind of sort on a list of numbers based on frequency.   Answer Question

    I attended an open house at the DC location, then spoke to representatives at a career fair. Palantir was very no-nonsense, and asked me two questions regarding data structures at the career fair table that caught me off guard.

    I saw from the reps expression that I had been rejected on the spot, and received an email confirming my original impression a few days later.
