    Application Details

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

    Interview Details

    Hiring process consists of two interviews on seperate days.

    The first day is divided into several parts.
    On the first part you get to do two programming tests. The first one consists of finishing up function implementations using basic functions (equals, increase, assign, loop) and similar to assembly.
    On the second part you need to implement linked list in java. All tests are on paper.
    Those who passes the tests go to see their warehouse and go the interview with the HR person.

    If the HR interview was successful you get called for the second day interviews. There are two interviews but they are quite similar. They analize your CV and ask basic question about it. There are usual HR questions like "What is your biggest weakness" or "The project you are most proud of" and questions based on technology you will be using: "Difference between C++ and JAVA". There wew also logical question and you needed to write code on the whiteboard.

    Application Details

    I applied through a staffing agency. The process took 3 weeksinterviewed at Ocado in September 2014.

    Interview Details

    I applied through a recruiting agency. The selection process starts with an online programming test via Codility. The test is made up of three tasks to be completed in one sitting. The tasks are not really hard, but you have to meet requirements about time and space complexity.
    I passed the online test and was invited to their assessment centre. Two paper-based tests needed to be passed: an aptitude test and a java based test.
    The aptitude test is not centered on any particular language. Some basic functions area provided to be used to implement more complex functions. In the Java based test, candidates are required to complete the implementation of a linked list. Both tests are not very hard, but be careful about edge cases.
    I passed the paper based tests and got on a tour to their warehouse.
    After the tour I had an interview with two team leaders. It was a technical interview covering knowledge of Java. I was also asked to write code on the whiteboard (needle in the haystack problem).
    The technical interview was followed by an interview with the Head of IT. It was an interview based on my CV and were I talked about myself and I could make questions about the job and the company.

    Application Details

    I applied through a staffing agency. The process took a dayinterviewed at Ocado in August 2014.

    Interview Details

    Passed initial screen and was called to assessment center. At first stage you need to complete 2 tests. The first test is logical test which is similar to assembly language coding which required to be done in an hour. These questions are quite tricky if you have no experience in writing assembly language codes. The second test is to fill in the missing methods for a linked list class which is easy.

    Interview Questions
    • The logical test is tricky, but I think as long as you have found out the techniques, it should be straight forward.   Answer Question

    Application Details

    I applied online – interviewed at Ocado in August 2014.

    Interview Details

    The first stage is a Codility test with three questions. The questions are not hard but you should be aware of the requirements on time and space complexity. After passed the Codility test, I was invited in an assessment day on August 2014.

    Just as other people said, a paper-based writing test need to be passed. The first part is some kind of low level language. Some basic functions are given, and you need to use them to finish other functions. The second part is a Java implementation of linked list, not very hard. Both parts are not hard, but the edge cases must be carefully considered. I say this because I figured out all of them but finally failed, which I think is because my careless to the edge cases.

    They are quite strict on their filter process, only one guy was successful in the paper-based test. People are friendly, and their CFC is brilliant.
