Uber Interview Experience

This Year around February Uber came to my college to hire for an SDE intern role. Uber team conducted coding around and asked 3 DSA coding questions, listed below:

• https://leetcode.com/problems/burst-balloons/
• https://stackoverflow.com/questions/1761626/weighted-random-numbers
• Last was a bit easy like finding the maximum sum.

After the result was announced and I was selected for an interview process :

Round 1: DSA

The interviewer began by asking me to introduce myself and share insights about his team.
–Next, he asked a question and the solution initially appeared to be related to binary search. I spent around 30 minutes discussing and considering the binary search approach. However, realizing that I was struggling, the interviewer provided a helpful hint to try solving it using the sliding window technique. I solved it using the hint and the interview was happy with the given solution.
— Next, he asked me something very very similar to https://leetcode.com/problems/pacific-atlantic-water-flow/, I told him my approach and since we were short of time I only gave him the pseudo-code.

Round 2: DSA + CS Fundamental

In this round, the interviewer focused on topics such as threads and object-oriented programming (OOP) concepts, engaging me with a series of insightful queries. Additionally, He asked me a medium-level tree question which was the question was similar to (Maximum Width of Binary Tree) on Leetcode. I have solved this question easily.
Overall, I felt quite confident about my performance in this round.

Round 3: HR Round

During this round, the interviewer focused on my current project and asked several questions to gauge my hands-on experience and knowledge. There were numerous cross-questions designed to assess my understanding of the work I had undertaken thoroughly. The interviewer also posed several behavioural questions to gain insights into my approach and mindset. I felt positive about this round as it went exceptionally well for me.

Results were announced, But unfortunate news that I had not been selected for the role. Yes, it’s true—I faced Rejection. It’s difficult to put into words the feeling of disappointment and sadness. However, I acknowledge that rejection is an inevitable part of life’s journey.
