The interview process with Ocado was the most humiliating and degrading experience I have come across.
My interview time was moved twice in priority of other candidates (personally, I think it was extremely unprofessional to have been told this). The second time it was moved I was not even notified. I had sat in the online meeting for 15 minutes frantically calling the Ocado recruitment team 3 times and it wasn't until I emailed them when no one picked up that I received a call back explaining they had forgotten to tell me of the time change as another candidate had been scheduled in at my time.
When I was in the interview, a technical assessment was sprung on me unexpectedly - at this point I had been unemployed for 3-4 months and I had made clear my skills were basic. In the end I decided to end the interview as my skills were not up to scratch and I didn't want to waste anyone's time. Had I been informed, I would have had time to brush up on my skills.
The interviewer was extremely polite and understanding despite the embarrassing situation.
The following day, I sent an email outlining my feedback and improvements that could be made to prevent others from going through this same experience, something I thought was very important considering the current situation where so many people are unemployed and just trying their best to get their life back to normality. I strongly suggested to give others the opportunity to showcase their best skills and experience by giving all candidates the necessary information in a timely manner.
Unsurprisingly given my experience with the Ocado recruitment team, my email was never acknowledged nor responded to and an official apology was never provided.
