Graduate Software Developer Interview

Application Details

I applied online. The process took 3 weeksinterviewed at Ocado in May 2014.

Interview Details

Applied online and heard back quickly. Scheduled Phone interview. Successful and invited to assessment center. Assessment center consisted of java linked list questions and assembly style math/logic questions all in a paper test. All you have to do is complete the methods (fill in variables and operators) and implement some classes fully (insertion etc). Out of 8 of us, 3 of us made it through to the second half of the day, don't know what happened to the others. The 3 successful got a tour of the local fulfillment center followed by an interview with a developer. Was then contacted again to arrange final stage interviews, all quickly and promptly. Had an interview with two team leaders covering knowledge of Java (JVM, methodologies, garbage collection) and a few board exercises (fibonachi numbers). Last interview with Head of IT based on my CV and HR questions with two logic problems to solve.

    Graduate Software Developer Interview

    Application Details

    I applied through a staffing agency. The process took a dayinterviewed at Ocado in July 2012.

    Interview Details

    Initially I received a call from an recruitment agency. I took an online programming test on codility. After passing that, I got an offer to attend an interview day. Arrive at least 1 hour before the interview at the Hatfield railway station, because the bus takes 20-25' to get to the square. First we were welcomed by an HR member who took us to the testing room. There, we were handed two tests. We had maximum 45' for each. After completing the tests, a leader of one of the groups came and talk to us about the company, while our tests were getting assessed. After about an hour they came back and I got a negative result, so I left.

    The two tests were consisted of a pseudo code made up language and a Java test. The pseudo code one gave you 4 functions and you have to create all the remaining functions using those 4 functions while filling in blanks mostly. If you have any experience with assembly is quite similar but easier. The Java test is a basic linked list implementation where you have to create additional methods by filling in blanks again. Read a bit about linked lists, how to add elements in an unordered & order linked list and to the begin and end of it, how to use recursion to calculate the size etc.

    The tests seem to be the same for the last 1-1.5 years because I had friends taking them as well.

    Negotiation Details
    I asked the recruiter what salary range they would consider, he gave me a range, I said I wanted the top figure of the range, and they came back with that as an offer. Thinking back maybe I could have asked for more.
