Recent interview experience with British Petroleum (BP) for Data Analyst Role (21 LPA)
Summary
I had an interesting interview experience with BP for a Data Analyst role, where a seemingly simple question about finding a peak in a bitonic array with duplicates challenged my understanding of algorithm limitations.
Full Experience
I recently interviewed with British Petroleum (BP) for a Data Analyst role. The experience was quite insightful, particularly due to one specific question that tested not just my coding ability but also my understanding of algorithm complexities and how data patterns affect them.
The question involved finding a peak element in an array that first increases and then decreases, with the crucial added complexity of allowing duplicate values. This problem made me think beyond typical optimizations and truly evaluate the limits of common algorithmic approaches.

In an array that increases and then decreases, how do you find the peak element - even if duplicates exist?
