Round 1 - Problem solving Round [~80 mins] :
This round was with another Lead Engineer. Totally two problem solving questions + domain specific question were asked.
Q1. Implement Polyfills for array methods , promise.all
Q2. Implement counter using setTimeout. Implement debounce. Implement sum(1)(2)(3)();
Q3. There are various JS specific questions related to hoisting , this etc.
This was a very lengthy round and interviewer asked almost everything he knew :)
Round 2 - System design [60 mins]:
This round was with a Director. I was suprised that a Director is taking a technical round. We started with introductions. He explained his work profile , scope of his work etc.
Then he asked to design a platform for rental service. He was expecting a detailed information about the APIs, contract for it , UI components, the entire funnel flow from login to booking.
We had a very good discussion for almost 1hr . We also discussed about perofrmace , measuring app interaction , crash reports etc. Overall it went really well.
Since Both the rounds were having Must Hire Feedback so they skipped the third round and I got confirmation that I was selected.
Though I asked the recruiter that I need HM connect one more time to calrify my doubts :)
Then I had HR discussion about my expectation etc.
