I applied online. I interviewed at Uber (San Francisco, CA)
Interview
Initial call with a recruiter to go over position. Then was given 1 week to complete a coding challenge on CodeSignal. It's 1 hour and there are 20 questions, so you need to make sure that you have time and the mental capacity to essentially take an exam.
I didn't realize what I was signing up for and took the exam at a bad time. Didn't really give that much effort but never heard back from recruiter.
Interview questions [1]
Question 1
3 programming questions and 17 JS trivia questions. You need to operate at a pace of about 3 minutes per question
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.

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).
