Uber Technical Interview Questions For Freshers

1. What is normalization in SQL?

The normalization process improves the integrity of the data in the table by eliminating redundant and duplicate data. Moreover, normalization aids in the organization of database data. It takes multiple steps to transform the data into tabular form and destroy duplicate data from relational tables.

2. What is the difference between backup and redundancy?

A backup is a replica of your organization's data created expressly for usage if a data loss occurs. Yet redundancy includes a lot more than just data archiving. Redundancy ensures that your company can continue to provide services under any circumstances.

3. What is a Hash Map?

A hash table or a hashmap in computing is a data structure used to create an associative array or dictionary. It is abstract data in which values are linked to keys. A hash table uses an array of buckets or slots to create an index, commonly called a hash code, from which the desired data can be obtained. While doing a lookup, the key is hashed, and the resulting hash identifies the location of the pertinent value.

4. What does "Excellent Customer Service" mean to you?

Like any company, Uber strives to attract clients by providing quality services. To succeed in the interview, you must persuade the interviewer that you can efficiently serve and please customers. Whatever your line of work—driving, food delivery, or developing mobile apps—this is applicable. Demonstrate your dedication to leaving the consumer happy.

5. Find the square root of the number up to the given precision using a binary search

function squareRoot(number, precision)
    {
        let start = 0, end = number;
        let mid;
        // variable to store the answer
        let ans = 0.0;
        // for computing an integral part
        // of the square root of a number
        while (start <= end)
        {
            mid = (start + end) / 2;  
            if (mid * mid == number)
            {
                ans = mid;
                break;
            }
            // incrementing start if integral
            // part lies on the right side of the mid
            if (mid * mid < number) {
                start = mid + 1;
                ans = mid;
            }
            // decrementing end if an integral part
            // lies on the left side of the mid
            else {
                end = mid - 1;
            }
        }
        // For computing the fractional part
        // of square root upto given precision
        let increment = 0.1;
        for (let i = 0; i < precision; i++) {
            while (ans * ans <= number) {
                ans += increment;
            }
            // loop terminates when ans * ans > number
            ans = ans - increment;
            increment = increment / 10;
        }
        return ans;
    }
// Driver code
        // Function calling
        document.write(squareRoot(50, 3) + "<br/>");
        // Function calling
        document.write(squareRoot(10, 4) + "<br/>");

6. Write a program to reverse the digits of an integer.

n = 4561
rev = 0
while(n > 0):
    a = n % 10
    rev = rev * 10 + a
    n = n // 10
print(rev)

7. What is Dynamic Pricing?

Dynamic pricing is a strategy that sets different rates for the same good or service for customers based on market trends and demand. Businesses can respond to changes in supply and demand by dynamically changing their prices in real-time.

8. What are nested queries in SQL?

A SQL query is an operation that includes a SELECT statement that retrieves information from a database table. A nested query is a whole query that is embedded within another action. A nested query can be created by nesting each valid query inside another operation containing all the elements in a standard query. For instance, nested queries may be present in the INSERT and DELETE methods. A nested query should be embedded by enclosing the statement within the proper number of parentheses to follow a specific order of operations.

9. What is a stationary signal?

A stationary signal is a wave created by keeping the time and spectral content value in a fixed connection. Software or a function generator can generate a sine wave from a stationary source.

Stationarity describes the relationship between a signal wave's frequency and temporal components.

10. What is your course of action if you face JavaScript performance issues?

  • Minify Your JavaScript Code.
  • Reduce your use of the DOM.
  • Switch to HTTP/2.
  • Only load JavaScript if it is essential.
  • Use performance improvement tactics that work with other languages.

11. What are the 5 assumptions of Linear Regression?

A linear regression analysis examines the dependent (criterion) variable to see if one or more predictor variables can adequately account for it. The five assumptions of linear regression:

  • Multicollinearity
  • Homoscedasticity
  • Linear relationship
  • Multivariate normality
  • No auto-correlation

12. What do you mean by Microservice?

Microservices architecture, often known as the SDLC approach known as microservices, is the development of large applications as a collection of distinct functional modules. It is one of the architectural concepts that are most frequently utilized in software development. Its architecture expedites simple maintenance in addition to accelerating growth. DevOps and Agile, two of the most contemporary software development methods, greatly benefit from microservices.

13. State your understanding of Distributed Database Management Systems with Transparency.

A distributed database is simply a database that isn't limited to just one system and may be found in multiple locations, such as several computers or a computer network. It has a database-like appearance. A distributed database system has several sites that don't share physical components. This can be necessary when several people worldwide access the same database. It needs to be handled in an approachable way.

Transparency in a DDBMS refers to the transparent transmission of information from the system to the user. It helps to mask the information that the user needs to use.

There are four types of transparencies in Distributed Database Management System:

  • Transaction transparency
  • Performance transparency
  • DBMS transparency
  • Distribution transparency

14. What exactly is a Bootstrap Program in terms of operating systems?

A bootstrap program is the first line of code to execute when a computer system boots up. Since it loads the operating system, the bootstrap software is crucial for the operating system to function properly.

The bootstrap program is demonstrated in the following figure:

Bootstrap Program

In the image above, the ROM, or non-volatile Memory, contains the bootstrap program. The bootstrap program loads the operating system into RAM when the computer turns on. The operating system then starts the device drivers.

15. What do you know about demand paging in the OS?

Demand paging is a technique that moves data from secondary Memory to RAM when needed. Demand paging is utilized instead of RAM since it has limited space, and not all data is saved. Swapping is, therefore, necessary if the CPU requests a process and the requested page is not present in Memory. This will transfer the old page from RAM to secondary Memory, return it, and put the new page in RAM.

16. What is VPN (Virtual Private Network)?

A "Virtual Private Network," or VPN, is the ability to create a secure network connection while using public networks. VPNs mask your online identity while encrypting your internet traffic. As a result, it is more difficult for outside parties to monitor your online activities and steal your data. Real-time encryption is utilized.

17. In the context of operating systems, define microkernels.

The primary part of an operating system, or kernel, is in charge of controlling system resources. It also acts as a bridge between the hardware and software of the computer. This is one of the earliest programs to launch (after the Bootloader).

The microkernel is one of the kernel's divisions. Being the kernel, it has control over every resource in the system. Yet, a microkernel implements user and kernel services in various address areas. The Kernel and operating system sizes are decreased by keeping user services in the user address space and kernel services in the kernel address space.

It provides the most basic Memory and process management capabilities. The usage of message forwarding slows down microkernel operations to promote communication between client programs/applications and services running in user address space. The Operating System is unaffected if user service fails because user and kernel services are isolated. Hence, it enhances one advantage of a microkernel. Since it is easily extendable, any new services added can be modified in the user address space rather than the kernel area. It is also reliable, secure, and transportable. The L4, QNX, and MINIX operating systems are examples of microkernel-based operating systems.

18. What is the difference between Swapping and Paging in OS?

Paging, a memory management technique, allows systems to store and retrieve data from secondary storage for primary memory usage. Contrarily, swapping briefly switches a process from primary to secondary Memory.

19. What is Servlet Collaboration?

The method through which the servlets of a particular Java web application interact with one another is known as servlet collaboration. As a result, information can be transferred or sent across servlets via method calls.

The servlet api provides two interfaces, namely:

  • javax.servlet.RequestDispatcher
  • javax.servlet.http.HttpServletResponse

These two interfaces include the techniques responsible for achieving the objective of information exchange across servlets.

20. What is Spooling in Operating Systems?

The operating system's CPU needed our input to process the instructions and generate the desired outcomes. With the conventional approach, the CPU would be quiescent, while one process used an input device to give the input. Yet, there was a downside to this tactic. Many operations must be managed in a typical situation, and we know that an I/O transaction takes much longer to complete than an instruction on the CPU.

The command is then executed by the CPU, which is now inactive once more, and the output is transmitted to an output device once more. After seeing the output, the next procedure starts to run. The upshot is that the CPU is frequently idle, which is the worst scenario for operating systems. Spooling is a concept that applies in this circumstance.

During spooling, data is momentarily stored to be used and executed by a system, program, or device. Data is supplied to and kept in Memory or another sort of volatile storage before being requested for execution by a program or machine.

The term "SPOOL" stands for "simultaneous peripheral operations online." The spool is often kept in buffers, physical memory, or interrupts for I/O devices. The spool is processed using the FIFO (first-in, first-out) method, which works in ascending order.
