Ocado Technology Graduate Software Developer interview questions

Coding test, Aptitude test, Video interview (All online) - Assessment Centre: 3 rounds in total, 2 coding rounds where they asked me to code in my chosen language, and the other round was a group activity which had nothing to do with programming and was just a small exercise to observe how you would work in a group setting.

first stage is a coding interview with the first question a lot harder than the second. the first was a simple array question while the 2nd one DP. pretty sure it was 2 dimensional dp aswell.
