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!
