Hey guys I will be briefly sharing my interview experience at Sigmoid Analytics. There were 2 technical rounds.
Round 1 Technical Round 1 Given an array, find the next greater element for all elements. I was asked to give an optimized approach. Given a tree, check if the tree is a Binary search tree or not
Round 2 Technical Round 2 Given an array of numbers, find the maximum product triplet. Different approaches were asked to optimize Check whether the string contains balanced parentheses. The questions were straightforward, but I realized that I made a small mistake in the first question of 2nd round, so could not make it to the HR round. All the best for your interview!
