I applied through an employee referral, received test link in 2 days.
Round 1
Hackerrank coding test, 2 question in 90 minutes. I don't remember the exact questions but both of them were leetcode medium level DP.
Round 2
It was a video interview. Interviewer first asked me about my current internship experience and discussed about few projects. Then few basic coding questions:
- Reverse the linked list, recursive and iterative.
- Reverse the linked list in parts.
- Intersection & Union of 2 arrays.
Interviewer asked for as optimized result as possible and also just writing function won't work. Need to write main and helper functions as well and then define the edge cases.
Round 3
Format was similar to the 2nd round. Here instead of internships, Interviewer was interested in OS and CN concepts, such as Paging, DNS server, Memory management. Coding questions:
- Given an array of integers, create biggest number by concatenating them.
- Find maximum path sum in a tree.
Here also, Interviewer asked to create struct and helper class for tree.
Round 4
It was hiring manager round. He asked about basic concepts of OOPs, OS, CN and few questions about DBMS such as sql vs nosql, indexing, etc. He majorly asked about the internship projects and then explained about the work at Hotstar.
Round 5
It was HR round. He majorly asked about my tech stack preference, location preference, and few basic cultural questions like why I want to join Hotstar, what other offers I have.
Got a call after 3 days of HR round regarding Selection.
