Question 1
https://leetcode.com/problems/construct-quad-tree/
I had to design the class and construct the function to convert the matrix to tree in 60 mins. Quite difficult if you dont know the concept of quadtrees
Got referred by a colleague from a previous project, which kickstarted the hiring process. It included a mix of technical rounds and a behavioral interview.

What helped me the most was the design walkthroughs I went through on PracHub; they were incredibly relevant. Overall, the experience was straightforward, and I ended up accepting the offer!
