Telephonic Screening : The questions were basically around CV. They were testing my fundamentals and the basic understanding of concepts and a medium problem solving question on google document. The expectation was to write production ready code. Round 1 F2F : 1. Deep dive into the projects to understand my responsibility and individual contribution. The questions were more around the leadership principles. Two medium problem solving questions one on array manipulation and other on trees. The expectation was to write a production ready code for one problem and detailed approach for the second. The interviewer was specific about all the edge cases. The interviewer was casual and helpful in the problem solving questions. Round 2 F2F : Detailed design and end to end working of the project. Many of the design concepts and design decisions were checked that were used in the project. I have used Caching and distributed databases in my project so I was asked many questions on CAP theorem , cache eviction policies why and how we used them in our projects. Then we went into low level design of a specific design question , it was a tweaked version of distributed cache but not straight forward , I think because I have worked on the cache based projects they have asked me this question. Questions were asked on microservices architecuture and databases as they were mentioned in my CV. Some questions were also asked on front end java script - I could not answer them as I was not into frontend. This round went very well. Director Round : This was the last round. I had the interview over Skype with the director from Seattle. There were a couple of problem solving questions and I was asked to write production ready code. I was asked a question on high level design and we deep dived into the design. This was a refreshing round touching a lot of things on my CV and my motivation to join a start up like environment and my ability to come up with a solution for an unseen realtime problem. HR Round : Again on skype , was with a HR from Dubai. Behavioural questions were asked.
