I applied through an employee referral. I interviewed at Uber (Palo Alto, CA) in Apr 2017
Interview
Telephonic Problem Solving and then Onsite Interview.
Most of the interviewer will pick the question from leet code like website.
The design interview was little weird, the interviewer himself got little confused with the requirements, and I thought it was too vague. I understand that for the design interview there should be some loose ends, but not everything should be loose.
Couple of interviewers were really rude. One of them, gave me a problem and start working on his laptop, as if he is not interested in the solution approach but just the solution. It felt more like a university practical exam with some invigilator.
Interview questions [1]
Question 1
Problems based in Binary Search.
Array Related Problems
Graph Traversal
The phone screen lasted about 30 minutes and began with general questions about my background before diving into technical topics. I was asked to solve a DSA question on finding the top K frequent elements, discussing both the min-heap and bucket-sort approaches. Surprisingly, I had recently practiced a similar problem on the algorithm section of PracHub, which helped me articulate my thought process clearly. The interview continued with an onsite where I tackled system design and behavioral questions, and overall, the experience was straightforward and positive, leading to an offer that I happily accepted.

Question 1
Top K Frequent Elements: given an integer array and integer k, return the k most frequent elements. Walk through both the min-heap approach (O(n log k) time) and the bucket-sort approach (O(n) time), then discuss the trade-offs in time, space, and which one you'd pick for a streaming variant where new numbers keep arriving.
Surprisingly, the interview felt quite straightforward, especially for a senior role. I started with a technical screen, where I was asked to design an Uber Eats cart service. It caught me off guard initially, but then I remembered a specific mock I had practiced on PracHub that was nearly spot-on with this scenario. The final round included some behavioral questions, and although I received an offer, I ultimately decided to decline. Overall, it was a positive experience.
I applied online. I interviewed at Uber (Bengaluru)
Interview
Round 1 - Coding
Question: Count Rectangle-Line Intersections. Given a set of rectangles and a set of vertical line segments, count how many places the vertical lines intersect the rectangle edges (ignoring edge-on-edge overlaps).
