How do you answer interview questions for Uber?

According to a Survey,

Around 70 percent of applicants are rejected after their first meeting with Uber's recruiters, with only around 30 percent getting through to the next stage of the recruitment process.

So if you've ever considered attending an Uber interview, you'll know it's not as easy as it seems on the surface. That's because many people get turned down after their first interview with the company.

Therefore, we have come up with this guide to help you with your Uber interview preparation. 

How to frame answers for the Uber coding interview questions?

One of the most important things to do before any interview is to research the company and what they're looking for in candidates. This way, you can tailor your answers to fit what they're looking for.

When it comes to technical interview questions, Uber will likely ask about your coding skills and abilities. They may also ask questions about specific technologies that they use, so it's important to be familiar with those as well.

With that in mind, here are some tips on how you can frame you answers for the technical interview questions based on the Uber coding interview:

Be confident in your abilities 

If you don't believe in yourself, the interviewer won't either. The key factor here is not to be relatable or portray that you know the answers to all the questions but rather to make sure that you can accept a few constructive criticisms during the course of your interview.

Practice ahead of time 

Take some time to brush up on your coding skills and familiarise yourself with the technologies that Uber uses. This way, you'll be able to hit the ground running during the interview. 

Practice for online mock interviews

Career counsellors and guidance coaches can be easily found all over the internet. The mock test sessions prepared by them can foster valuable soft skills for interviews within candidates who enrol for their sessions. 

Be prepared to discuss your experience

The interviewer will want to know why you're interested in working at Uber and what relevant experience you have. Be honest and concise in your responses. Their questions will be mainly focused towards your experience in your previous corporate roles. Try to draw your answers from your personal experiences and be as precise as possible. 

These are the basic fundamentals for preparing yourself for your Uber coding interview questions that will certainly help you along the way. Now, let’s take a look at a few questions that you will likely encounter during the interview.

Coding Questions to be asked in Uber Interview

From questions related to arrays to OOp to striver SDE sheets, you will come across various topics in programming interviews. 

Here are the most common uber interview questions you’re most likely to be asked:

1.What is an array?

An array is known as a data structure that helps store fixed-size collection of elements  which are of the same type. It is defined by its size and the type of its elements.

2. Which data structure would you use for finding all prime numbers smaller than n?

I would use a Sieve of Eratosthenes, which is an algorithm for finding all prime numbers up to a certain number.

3. What's the Big O notation?

"O" notation is a mathematical model for modelling the performance of a system. O(n) means that the larger the input, the more time it will take (exponentially). No matter how large the input gets, it will always take a constant amount of time (e.g., linear).

4. What is a linear list and what are its common implementations?

A linear list has a sequential ordering, often because it's one continuous sequence of items. The most commonly implemented implementations of a linear list are arrays, linked lists, and queues.

5. What do the terms "OOP" and "Hierarchy" refer to?

OOP refers to Object-Oriented Programming, which is a programming language style that places data and code together. Hierarchies exist everywhere in nature, and many computer systems are organised hierarchically. Levels of hierarchy can be nested; for example, a family tree shows a person at the top level (the parent), with their spouse and children below them on the next level (the child), and so on.
