I applied through a recruiter. I interviewed at Ocado Group (Hatfield, East of England, England) in Jun 2018
Interview
Because a spot had just opened up, I was allowed to skip the online coding test and was invited to the full-day assessment immediately. None of the tests were in them self too difficult, I gave the difficulty rating because it was 8 hours of tests and that is taxing when you're nervous.
Others have described that day before, so I won't repeat it all. I was asked to submit a logic test in a made-up language, had an interview with someone trying to gauge how well I'd fit in with the company culture (that felt more like a personality test than anything else), then got to see the warehouse (amazing), had a pair programming exercise where I had to implement some interfaces and make the tests pass, all while being monitored. After that, they proposed a complicated problem that you were to solve in exactly the way they had come up with before, so if you don't think like them, that's going to be frustrating. They help you though. After that, I had another technical interview, the same questions about Java you get asked everywhere. You have a Java certificate and already proved you know all this? Not worth the digital ink its printed in, nobody will believe you know your stuff until they've asked you similar questions. After that, I had another interview with the head of the department. By that time, it was 5:30 and I was really tired after a day of being on your best behaviour. They told me they'd get back to me within a day or two, but it's been 4 weeks and they never have. At this point in time it's obvious no offer will be forth-coming. I just wished they would have had the courtesy to call and say I didn't make it after I took a day off work and spent 8 hours trying to pass their many tests. A very disappointing experience.

Question 1
In Java 8, what happens to the stream if you terminate it or don't terminate it?
I applied online. I interviewed at Ocado Group (Kraków)
Interview
I don't remember every aspect of that interview well, but I know there were a few deep-level questions about how data structures work. Interview was conducted by two devs. It seemed formal and the atmosphere was rough.

Question 1
Why array elements are instant access when you know their index?
The first stage was quite a hard test task. Then I was invited to the second stage for an interview which did not go well for me. The conversation was conducted in a friendly atmosphere
Reached out by hr and scheduled first round. Everyone I met are very friendly but their interview is not typical and the algorithm question I got is a bit tricky.
So the first round has two parts. First part they ask some java, oop, design and db related questions. They cover quite a lot topics. This requires some time to prepare if you want to cover everything. Just from a candidate point of view, I feel it’s not worth to spend time preparing so much for one single company in a hunting season because you probably won’t be asked elsewhere. Second part is a algorithm question but a tricky one. I don’t remember exactly but it’s like you have the answer immediately after you understand the questions, but you tends to overthink because of the context.
