I applied through an employee referral. The process took 1 week. I interviewed at Uber (San Francisco, CA) in Jan 2014
Interview
I had three total sessions. The first two were technical (problem solving) which required whiteboarding. They were conducted with pairs of interviewers and lasted about an hour each. The difficulty was reasonable and I made a few mistakes but ultimately did well. The third session was with the director of engineering of the team and wasn't really an interview. He just told me that I essentially got the job and was done.
Overall pretty easy compared to Google, Facebook, etc. But keep in mind that this was early 2014. Now, the bar is much higher and the process is much more formal. Don't expect to just wing it; you should practice and take the interviews seriously now.
Interview questions [1]
Question 1
Basic problems that weren't too hard. If you understand basic recursion and data structures you'll do fine.
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).
