I applied through a recruiter. The process took 3 weeks. I interviewed at Uber (New York, NY) in Oct 2018
Interview
The whole process is not professional. The interviewer didn't call at first time as scheduled, and no recruiter follows me up until I asked. The phone interview asked two technical questions and coding on shared document. I resolved questions and still got rejected and they refuse to share the feedback. There was less communication during the interview and the interviewer was doing something else. It feels like a teacher is watching you are doing an exam, instead of communicating ideas.
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.
Interview questions [1]
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)

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).
