An anonymous candidate shared their SDE-1 interview experience for Aditya Birla Group (likely pertaining to Birla Pivot given the context of the search). The candidate applied through the company's official website.

The candidate was rejected because they could not provide the optimal approach for a problem.

Coding Problem Asked:

The task is to find the minimum number of taps that should be open to water the whole garden, return -1 if the garden cannot be watered."

• Focus on technical skills relevant to the profile during discussions.
