So, generally all rounds starts quickly after 2-3 minutes of introduction. And last 5-10 minutes are kept for discussion/QnA.
1]. Problem Solving Round
Here one problem was given to run only n number of jobs simulataneously. So, one job finishes, pick up next pending job from job pool. It was expected to be written in vanilla JS. I finished in ~35 minutes
2]. DSA Round
It was exactly the same problem. I informed interviewer that I solved the same question in previous round, interviewer could not find any other question from the question bank. Strange :(.
It was little bit modified problem. I did it well.
3]. System Design Round
Design a pipeline for Uber Eats.
In a given city, let's after order created by user on Uber eats app, if that order is not accepted by restuarant within 2 minutes, show it on dashboard.
So, basically backend and frontend both were required to be designed.
In frontend, structure of redux store, basic UI skeleton was expected
Whereas in backend, how and where the data will be stored and how the user/customer executive will get the data.
During this round, keep whiteboard of your choice ready.
I gave table schema, few approaches and queries. To send the data to customer executive, used WebSockets.
4]. Hiring Manager Round
All behavioural questions
Any conflicts in past, how you resolved it.
Views on Mentorship
One of the best impactful work from your past
Critical feedback given/recieved.
5]. Bar Raiser
After 2-3 minutes of initial greetings, I was told to describe architecture of my current project.
Mostly catch here is, interviewers being an backend engineers mostly, they do not understand intricacies of Frontend projects.
Wrapped up in 45-50 minutes.
Overall, except the Bar raiser interviewer, everyone was really helpful, courteous, smiling throughout the interview.
It was good experience. It took 1 month to get the results after lots of follow ups from Recruiter, though the recruiter was very very polite and helpful.
