Uber Interview Process
The Uber interview process, like all interviews, starts with you applying for a job role. Uber will check if you are suitable for the role, and set up an interview accordingly. Recruiters at Uber also suggest positions that might suit your profile better than what you applied for.
Once you’re shortlisted, you’ll go through a technical phone screen and on-site interviews.
In most cases, the duration of each phone screen and on-site interview is 40 minutes.
Phone Screen/Technical Screen
The phone screen includes a coding exercise. Your interviewer will read your codes with HackerRank as you keep working. You can use a programming language of your preference to solve the problem. If your interviewer is not familiar with the language you are using, you’d have to explain your code, in addition to explaining the logic.
Note: According to Uber recruiters, a common query they receive during this round is whether it is okay to use outside libraries in your solution. We recommend using a standard library. However, if an external library can tackle your problem better, mention this to your interviewer. This will help them understand your expertise in the chosen language.
The Hardest and Easiest Programming Languages to Learn for FAANG Interviews
The Uber on-site will include 4-6 face-to-face interviews on the trot. Your interviewers will either ask you to use HackerRank or a whiteboard to solve the problems.
Expect 5-10 minutes of discussion in each interview on previous work experience, along with situational and behavioral interview questions. The final 5-10 minutes is for you! Ask the interviewer about the job role. Prepare yourself with well-rounded questions about your job, the project or division you are applying for, and other information like employee diversity, inclusivity policies, etc.

Uber Coding Interview Questions
Be prepared to face questions like the ones below during your coding interviews at Uber.
- You are given a 9x9 2D matrix with some empty cells (denoted by 0) along with cells filled with digits (1-9) such that the final matrix is a valid Sudoku solution. (Solution)
- Given a two-dimensional boolean matrix, find the number of islands. An island is a group of connected 1s or a standalone 1. A cell in the matrix can be connected to up to 8 neighbors: 2 vertical, 2 horizontal, and 4 diagonal. (Solution)
- Implement a queue with two stacks. (Solution)
- You are given an array/list of unsorted ARR of N integers. Return the length of the longest consecutive sequence. The consecutive sentence in the form ['NUM', 'NUM' + 1, 'NUM' + 2, ..., 'NUM' + L], where ‘NUM’ is the starting integer of the sequence while L + 1 is the length of that sequence. If we find duplicates in the array, we will consider only one of them in a consecutive sequence. Like, for the given ARR [9,5,4,9,10,10,6], output = 3. Here, the longest consecutive sequence is 4, 5, 6. Can you also solve this in 0(N) space complexity and 0(N) time?
- You are given a binary tree of integers. Print the right view of this binary tree. The right view of a binary tree is a set of nodes when viewed from its right side, while the nodes are printed in the top to bottom order.
- A group of friends went on a trip and lent each other money for various purposes. The tuple (X, Y, Z) represents each transaction, i.e., person X gave person y $Z. Given a list of 'N' number of transactions, return the minimum number of transactions required to settle the debt.
- Delete Edge to minimize the difference in subtree sum.
- Find the Max Rectangle in a Histogram.
- How to determine the max product of three numbers?
- What is Contiguous Subarray Sum?
- Merge two binary trees.
- Implement a hash map.
- Write an efficient and effective function that can check whether a permutation of any input string is a palindrome.
- Write a function to find an index of a rotation point in an array.
- Write a function fib() that will take an integer n and return the respective nth Fibonacci number.
- Check whether your single-linked list contains a cycle.
