Very Difficult Interview

Software Engineer Interview

Software Engineer

I applied through a recruiter and the process took 3 weeks - interviewed at Palantir Technologies.

Interview Details – Was contacted by a recruiter, whom I emailed back in a few days. HR interview went fine but the technical interview was very difficult. A few weeks later I received an email that they moved on. By far the most difficult technical interview so far.

Interview Question – I don't want to give the question away, but it was about a data structure that is almost never used in production code and which I didn't even study for.   Answer Question

Interview Details – Contacted by a university recruiter as part of their annual new-grad hiring process. Had a couple of phone interviews before they flew me out to the valley for a day's worth of interviews.

Interviews were quite tough, they grilled me on Java - something which I was not too familiar with.

The kitchen was awesome, though!

Interview Question – I couldn't answer several of the Java OOP questions that were asked. I wish I had read up more on the intricacies of access modifiers, etc.   Answer Question

Interview Details – I think the interviewers are not very experienced and professional. They tend to show off their *high* IQ instead of focusing on the interviews. However, the recruiters are great and patient. They explained things well and tried their best to make the interviewee as comfortable as possible.

I applied online and the process took 2 weeks - interviewed at Palantir Technologies in June 2014.

Interview Details – Very good experience overall.
Applied through the website, there was a coding exercise to complete within 2h.
Not too difficult if you are trained to interview and you know your algorithms well.

After a couple days, first contact with HR, a phone screen with some coding/algorithm.
Onsite a week after with interviews all day. If you are doing well, you will know along the way, engineers/hr seem to communicate between them.
At the end of the day I met with a funder and I had an offer the next day.

Interview Question – Nothing difficult, everything standard and straightforward if you know basic algorithms + data structure.   Answer Question

The interview was not easy for me. But I like Palantir's atmosphere and its location. For onsite interview, it includes breakfast and lunch.

Interview Question – The most difficult question is about a algorithm question, and the ways to test it.   Answer Question

Software Engineer Interview

Software Engineer
San Francisco, CA

I applied online and the process took 4+ weeks - interviewed at Palantir Technologies in April 2014.

Interview Details – I applied for one of the positions on their website and got a followup from their recruiter. After that, I had a phone interview with them. Then I was invited to their onsite. The conversations did not go on well and I myself cannot see myself a fit for their company. They ended my interview after 4 rounds.

Interview Question – Some of their questions are quite open-ended and not well defined. I spent too much time clarifying what they really want. In general, I feel that the engineers do not have a clear picture on what they are doing and are not as smart as a few other companies I am interviewing with.   Answer Question

I applied through college or university and the process took 1 week - interviewed at Palantir Technologies in November 2013.

Interview Details – Initiated contact at a career fair. They asked me a technical question at the fair. The question was: You have a set of (time,value) pairs. How can you find the first and last values in the time interval [a,b]. Answer: You do binary search. Then I was called to an on campus interview. I didn't get further than that.

Interview Question – Print a binary tree using breadth first search, i.e. print all numbers level by level on a tree. Add a line break between each level.   View Answer
