Answer 1

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.
