Average Interview

Application

I applied online. The process took 3 weeksinterviewed at Ocado.

Interview

Online test, followed by by written test then interview. Still waiting to hear back from the interview so I'll update that after. If you passed the online test without cheating I don't see how you can fail the written test as it's much easier than the online test! Everyone is nice and friendly which put my nerves to ease, helps a lot for the interview.

    Application

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

    Interview

    Codility test with three questions first, wasn't hard if you have done some of the codility questions before. Then the assessment day in their head office which last about 4-5 hours in total. 1. Two paper based tests, first one is low level language like, which is quite time intensive, I have managed to finish the test just 10 seconds before the time ran out. Second one is java specific, if you understand linked list well, then you have no problem doing it. 45 mins for each test. 2. Face to face interview with three software developers, this is a very technical round, don't be nervous because they are very friendly people. It seems like they don't have many standard questions, they do ask questions base on your previous experiences and the skills you put on your CV. It also invoked to write some code on the board, in my case the room does not have a white board so we used paper instead. This round last about an hour. 3. Face to face interview with their department manager, very friendly and nice guy again, nothing too technical, he asked some basic background questions like why do you choose programming or computing at the first place, he also explained what project does the company currently doing, asked what would you like to be get invoked into, very nice interview indeed.

    Application

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

    Interview

    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.

    Difficult Interview

    Application

    I applied through a staffing agency. The process took 1 dayinterviewed at Ocado (Hatfield, East of England, England (UK)) in July 2012.

    Interview

    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.

    Application

    I applied through a recruiter. The process took 4+ weeksinterviewed at Ocado in June 2011.

    Interview

    Initially an online test, then invitation to assessment day. This consisted of two tests, one java and one in a made up language. The successful candidates proceeded to have tour of warehouse, and short interviews. Next invited for second interview, this included technical tests with two interviewers asking whiteboard based questions, and a couple of interviews with managers about personality and circumstances. Received an offer two days after the second interview.

    Negotiation

    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.
