Let me share my experience with Delivery Hero interview which I have attended. I will not be able to share the exact questions but will try to give the idea on the process and all.
There are 5 rounds for me all together - Online Coding Test, Technical Interview with a Sr Engineer, Technical + Behavioral with Hiring Manager, Bar Raiser Round 1, Bar Raiser round 2

Online Coding Test :
This round will have questions on coding and I was having 4 questions to solve in 75 mins. Questions are not that difficult, it is Leetcode easy and medium standard. Eevn you don't solve all problems it is still good I guess, for me I could able to solve 3 out of 4 problems. Some prblem statements are big and need to be thorough. Time does not matter here, you do have ample time to solve problems.
First Technical Interview :
This was 1 hour interview. They will focus on your current role and projects, Your design Skills and Best Practices, Understanding on the the different Architectural Partterns used in your roles etc and a coding problem at the very end. The coding problem is not that difficult may be Leet code Easy or Medium which can be solved in 15 min easily
Hiring Manager Round
This round mostly focused on the behavioral and scenario based questions that we are facing in day to day basis in work place. One System Design question and how to approach to that (clarify what is the expectations clearly) and at the very end discussions on the Online test that I appeared for screening
Bar Raiser 1
Once you are through to the first two interviews Bar Raiser will be scheduled for you. In this round first part are similar to the Hiring manager round but at the very end asked me a coding question but that was pretty easy and can be solved in 5 mins, asked some different scenarios on that questions and how well you are considering those in your approch matters what I feel i.e. how extensible is your code is.

Bar Raiser 2
What I know there is only one Bar raiser but may be one extra as it was for me. This was on mainly scenario based on behavioral as well as for a Technical Leader how will you go about on any problem in hand i.e. while you are going to lead a team for a new initiative etc.

Once all the rounds are done they came back to me in 2 days for HR discussion on next steps. For me it was positive feedback and they extended me the offer. Delivery Hero is very quick on moving from one round to another. I have overall good experience.

Please let me know if this helps. This is my first post on interview experience, tried to cover all aspects, still if you feel something more could have been helped please let me know.
