Round 2:
He asked about my project in detailed and focused on how I implemented the functionality of few key things. Gave to write a proper c code of

first, I gave a O(n^2) approach then he said to optimize it. then I gave O(nlogn) approach by sorting the array and then using binary search for finding(arr[i] – k) where k is the given sum.

Round 3:
From some this round was HR and for some it was tech. for me it was tech.

asked few c++ questions and difference between c/c++/java and few puzzles.
