The two interviewers were nice and walk me through the problem. But I didn't figure out the second problem(run out of time).

    Software Engineer Intern Interview

    Anonymous Interview Candidate in Palo Alto, CA
    Anonymous Interview Candidate in Palo Alto, CA
    Application Details

    I applied through a recruiter. The process took 2 weeksinterviewed at Palantir Technologies.

    Interview Details

    A recruiter wrote to me on LinkedIn about job offerings. I decided to go forward with an internship application. During the process I talked with three different recruiters -- all of them were very kind and one of them invited me for an 1-hour lunch/tour.

    I got a technical phone interview. I didn't get the impression from the interviewer that he wanted to do interviews and he may not have done a lot of interviews. Maybe he was as nervous as I was, I'm not sure.

    I ended up using Java even though I was told by the recruiters that I could use any language (I specifically asked about C++ and C#). I have no problem with Java programming but at the time of the interview I hadn't used Java for a year. I did okay on two questions and wrote a solution for another question that I improved with a few hints. In the end I asked standard questions about culture, etc. But also a more bold question about his impression of the handling of the NSA/Wikileaks cases. Those issues means a lot to me.

    A day later I got a standard email from Palantir (not from any of the three recruiters or from a physical person!) telling me that they didn't see my experience/skills fit the position. I think that was very unrespectful. When I (and one of their engineers) use 45 min for a phone interview, I think the least they can do is to use 3-5 min to tell you why they didn't see you fit such that you can improve, etc.

    I wrote to one of the recruiters about it and after a few emails I got more details. While I don't agree on all the points, I was satisfied to get an explanation. The explanation from the recruiter made this a neutral experience instead of a negative one.

    Software Engineer Intern Interview

    Anonymous Interview Candidate in Palo Alto, CA
    Anonymous Interview Candidate in Palo Alto, CA
    Application Details

    I applied through college or university. The process took 3 weeksinterviewed at Palantir Technologies in March 2013.

    Interview Details

    Had phone screens and onsite interviews. While both were technical, the phone screen was a lot more intense than the in-person interview. They were both entirely algorithmically focussed and for some odd reason.

    The on-site interviews were all coding-based – they asked me questions that looked initially easy but blew up in my face, and questions that were just hard from the beginning. I had to ask for help for at least a quarter of them, and the interviewers also helped me debug 2 of them. I couldn’t answer one. I must say that it was, though grueling, an interesting, and in some ways, a fun experience.

    Interview Details

    Met the recruiter at my university career fair. After a short talk I was told to take the coding challenge. Bombed the coding challenge, was followed up by a phone interview. The phone interview went great, and I got the concepts and the programming question correct. The guy seemed to really like me. 2 hours after the phone interview I received an email saying they didn't want to hire me.

    I applied through college or university. The process took 5 daysinterviewed at Palantir Technologies.

    Interview Details

    Spoke to a recruiter at a career fair and then set up a phone interview - I thought it went well but no offer. They only asked one very basic question which I fumbled on (thinking that it would be harder) and was turned down a day or two later. Bottom line for college students applying for internship positions: don’t get freaked out by how hard everyone says the interview is.

    I applied online. The process took 3 weeksinterviewed at Palantir Technologies in November 2012.

    Interview Details

    One phone interview followed by an in person interview at the Palo Alto location. The company is very good to its potential interns. When I interviewed at the location, there were about 25 other interns doing the same. Apparently they get this many potential interns on a weekly basis.

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

    Interview Details

    Applied online and received an email to set up a phone interview. They also provided helpful links to aid in preparation. During the phone interview, he asked about my resume a little bit before launching into the technical questions. Mostly data structures and algorithms questions, with a few general programming questions. I answered them as best I could, and unfortunately they found my programming knowledge to be lacking.

    Application Details

    I applied through a recruiter. The process took 2 weeksinterviewed at Palantir Technologies in March 2012.

    Interview Details

    I was scheduled firstly for an on-site interview because of a referral. Three days after that, I got a call from one of the interviewers that I would have a Skype phone call with the founder of the company a week later. Three more days after that Skype call, I got a call from that interviewer again, saying that I had an offer.

    The on-site interviews were all coding-based – they asked me questions that looked initially easy but blew up in my face, and questions that were just hard from the beginning. I had to ask for help for at least a quarter of them, and the interviewers also helped me debug 2 of them. I couldn’t answer one. I must say that it was, though grueling, an interesting, and in some ways, a fun experience.

    Overall, this company was pretty intense. One of the things I noticed first when I went for my on-site interview was that the employees loved coding, and the company of others who love working with tech like they do. They're all extremely smart, and they enjoy that extremely intelligent atmosphere - they can all hold each other up in projects, and also work on all kinds of different things. It also means many of them can interview you - when I went on-site, I was there for 9 hours, and was grilled by 5 different people, for 1 hour each.

    If you are going for an interview here, remember to be yourself. Though you will be interviewed alongside master’s student candidates, and maybe even people from out of the county, this is one of the most important things. Though it may seem like at such a high-stakes company, and you want to put your best out there, it is especially important to be real. Don’t stretch the truth about what you can or can’t do, and at the same time, don’t be intimidated by all of the flashy stuff (like a limo to the company, etc). They are looking for a good fit, and a good fit is a hard worker who is smart but doesn’t ruin their atmosphere of equality among all their workers. Sure, you’ll need a certain degree of professionalism to get this job, but this is equally important.

    • Say you have a single-column table of entries of variable size. Implement this table to also contain methods to lengthen one cell, cut a cell shorter, and to return which cell we're pointing at if given a certain distance from the beginning of the table. All methods need to be fast (assume a single-column table with many many entries).   View Answers (5)
