    Difficult Interview


    I applied through a recruiter. The process took 6 weeksinterviewed at Knight Capital (Santa Clara, CA).


    I was initially given a written tests, consisting of 4 programming questions/problems. Makefiles and (not necessarily comprehensive) test cases were provided.The test was un-timed, but we were supposed to report how long we took in completing it. My test took roughly 4 hours.

    We scheduled a phone interview about a week later. There were more technical questions, as well as the typical behavioral questions. At the end of the interview, I was asked to complete an implementation of one of the programming questions we discussed and send the result via e-mail.

    Soon after, I had a similar second phone interview. Again, a mix of technical and behavioral questions, with a post-interview programming exercise.

    I was invited to an on-site interview, which lasted for the entire day. I interviewed with 4-5 onsite software developers one-on-one, as well as with another developer in a different location via satellite and a group lunch. All of the interviews were technical (except for the lunch), with a mixture of brain-teasers, math problems, and programming exercises (using a notebook or whiteboard to write out solutions). Even during the video conference, I was grilled on material I'd mention on my resume.

    Knight made me a very competitive offer within a few weeks of interviewing.

    Overall, I was very happy with the entire process. All of the technical questions and tests were interesting without being overly burdensome, and I appreciated the extent to which they try to vet candidates. I was also very impressed with all of the employees I met. Overall, the atmosphere seemed relatively relaxed, but still meritocratic and productive.

    Interview Questions

    • Suppose you have a stack of pancakes of pairwise distinct sizes. You wish to order the pancakes the pancakes by size, with the largest one on the bottom. The only operation is available to you is a spatula flip: You can insert a spatula anywhere in the pancake stack and flip over the stack above the spatula, reversing the order of the pancakes. For instance, in the following stack

      bottom . 2 3 | 5 1 4 . top

      Inserting the spatula between 3 and 5 will give:

      bottom 2 3 4 1 5 | top

      Design an algorithm to sort the pancake stack using this operation. Write a program to execute this algorithm in C++. What is the runtime efficiency (precisely, not just in Big-O time), assuming that a flip is an atomic operation? Is your algorithm optimal (again, precisely, not just asymptotically)?

    Reasons for Declining

    I had multiple competitive offers, and another offer was better based on some other factors unrelated to the companies directly.
