Recently, Gameskraft Technologies Pvt Ltd. a startup founded by Prithvi Singh (NSIT) along with his friends and expert professionals from many companies like Grofers, Codenation, Amazon, etc. came to our campus to hire people for the role of SDE. Firstly there was a pre-placement talk about the gaming industry in India and how quickly it is growing. After that, we had 1 coding round followed by 3 rounds of technical interviews and 1 HR interview.
Coding Round: The first round comprised 3 coding questions of easy to medium level on Hackerrank. There were 3 questions in the online assessment round (90 mins)
- Maximize – OR – Sum
For an array of integers, arr[n], perform the following operation up to some i integer k times.
Choose an index i such that 1<=i<=n.
Replace arr[i] with arr[i]*2
The or sum is the bitwise-or of all elements in the final array after the operations. Return the maximum or-sum possible. - https://leetcode.com/problems/break-a-palindrome/

After the coding round, around 22 people were selected.
Technical Interview – 1: Two problems were asked in this 60 mins time. You have to discuss all the complexities from exponential to constant time –
- https://leetcode.com/problems/climbing-stairs/
- https://leetcode.com/problems/unique-paths/
Technical Interview – 2: One System Design question was asked to design typing master (i.e user was given a paragraph with the option to select difficulty to type the paragraph we have to measure the efficiency and speed of the user).
All the use cases must be discussed thoroughly and the backend is implemented in either C++ or Java.
Technical Interview – 3:Two problems were asked in this 60 mins time. You have to discuss all the complexities from exponential to constant time and also implement and pass the test cases:
