Have You Ever Made A Mistake When Programming Or Learning How To Code

Top 50 Software Testing Interview Questions & Answers | Software Testing Training | Edureka

Your candidates might select from a broad range of mistakes, including writing messy code and ignoring code quality, forgetting or deciding not to plan, or failing to practice. Whichever mistake they might have made, look for answers that indicate that they could learn to avoid these errors.

For instance, if your candidate wrote messy code as a beginner, which steps did they take to tidy up their coding quality? Did they learn about well-structured code, and how did they achieve this?

If they initially failed to plan before starting a project, did they actively seek to understand why planning is critical? And how have their current projects increased in quality thanks to the implementation of their new planning approach?

What Is Unit Testing

Unit testing is the process of testing a single unit of code in an isolated manner. The unit of code can be a method, a class, or a module. Unit testing aims to focus on the smallest building blocks of code to get confidence to combine them later to produce fully functioning software.

A unit test invokes the code and verifies the result with the expected result. If the expected and actual outcomes match, then the unit test passes. Otherwise, it fails.

A good unit test has the following characteristics:

  • It should test a single piece of functionality.
  • It is fully automated and repeatable.
  • It should run quickly and provide immediate feedback.
  • It should be isolated and shouldnt interact with external dependencies such as network, database, or file system unless needed. You can use the mocking technique to simulate the external dependencies and isolate the code under test.
  • What Are You Working On Right Now

    Find out what the software engineer is working on at the moment. Even if they are not currently working for a specific company, a good software engineer who is passionate about development will usually be working on a side project of their own.

    If they are indeed working on a private project, ask them why they chose that project, what their goals are, what they enjoy about that project, and what they are learning from the process of working on that project.

    What Are The Structure

    Structure-based testing techniques use the internal structure of the software to derive test cases. They are commonly called white-box or glass-box techniques since they require knowledge of how the software is implemented, that is, how it works. For example, a structural technique may be concerned with exercising loops in the software. Different test cases may be derived to exercise the loop once, twice, and many times. This may be done regardless of the functionality of the software.

    What Is The Most Helpful Feedback You’ve Ever Gotten About Yourself

    Top 10 software test engineer interview questions and answers

    Constructive criticism can be helpful for your overall professional growth, so consider answering this question with a piece of criticism you received and how it helped you improve your work. You can show your ability to react positively to constructive criticism and demonstrate that you’re willing to learn and progress.

    Example:”A year ago, my manager called me into her office and gave me some critical feedback that I wasn’t expecting. However, I am so glad that she pointed out a flaw in my organizational methods so that I could reevaluate my approach. While I didn’t realize it at the time, her criticism helped me challenge myself and improve my work without requiring me to work longer hours.”

    What Is A Bug In Software Testing

    A software bug is an error in the software that produces wrong results. A software tester tests the software to find bugs in it.

    There are many causes for the bugsfor example, poor design, sloppy programming, lack of version control, or miscommunication. Throughout development, developers introduce hundreds or thousands of bugs in the system. The goal of the tester is to uncover those bugs.

    You can find a bug in many different ways, regardless of your role. When building the software, the software developer might notice the bug in another module, written by another developer or by themselves. The tester actively tries to find the bugs as part of a routine testing process. Finally, the users could see the bugs when the software is in production.

    All bugs, no matter how they are found, are recorded into a bug-tracking system. A triage team triages the bugs and assigns a priority to the bug, and assigns the bug to a software developer to fix it. Once the developer resolves the problem, they check in the code and mark that bug as ready for testing. Once a bug is ready for testing, it goes to the tester, who tests the software to verify if its indeed fixed. If it is, then its closed. If not, they assign it to the same developer with a description of the exact steps to reproduce the bug. Some examples of popular bug-tracking systems include BugZilla, FogBugz, etc.


    What Aspect Of Our Company Product Or Team Interests You Most

    Retention is a high priority for many employers. Replacing a team member can be quite expensive in cost terms of recruitment and training time. Asking questions to ensure your interests and motivations align with that of the company can reduce the risk of losing you as a team member. Though youre ideally excited by the mission of the company, it is not uncommon for companies to use niche technology specifically to attract higher-quality talent. To answer this question, incorporate details from your research that speak specifically to the companys values, past projects or a responsibility mentioned in the job description that aligns with your career motivations and progression.

    Example:”I was watching an interview with your CEO about your product that aims to disrupt the lending industry. Streamlining arduous tasks like loan applications has huge potential. I think the growth in this sector over the last year is a big indication of things to come. Additionally, Im excited by the untapped potential of blockchain technology you have recently decided to incorporate. I see this as giving your company the competitive advantage in this space as the verifiable auditability will reduce compliance costs.”

    Can You Give An Example Of A Time You Needed To Solve A Conflict Within Your Software Engineering Team What Approaches Did You Use To Achieve This

    Conflict often occurs when communication is not clear, and solid conflict resolution skills are essential to diffuse tense situations.

    Senior software engineer candidates might cite examples where written communication has gone awry or where a code review has caused tension within the team and explain how they have stepped in to resolve this.

    Perhaps they encouraged team members to jump on a video call and acted as an intermediary between them. They might have encouraged their team members to think with an open mind or request the input of other team members and ask them to weigh in.

    What Is The Difference Between Severity And Priority

    These are important distinctions that must be known for proper time management. Severity is how difficult the issue is to fix. Priority is how important the issue is to fix.

    Just because an issue is high severity doesnt necessarily mean its high priority and vice versa.

    Heres an example of a high severity, low priority issue:

    • The application crashes when a rarely used function is run on legacy software that most users cant access.

    Heres an example of a low severity, high priority issue:

    • The wrong company logo is displayed on startup.

    Define What Case Means

    These four letters refer to computer-aided software engineering. This is typically a group of programs classed as automated applications that engineers use to achieve goals efficiently in the software development lifecycle.

    The best answers to this question will outline a few advantages of these tools, including the ability to keep the cost of the software development process low and boost the quality and chances of accomplishing the user’s requirements.

    Answer :Direct Memory Access is a feature provided by some computer bus architectures which permits data to be sent directly from an external device to the memory on the computers motherboard. DMA address deals with such physical addresses. It is an appliance which directly drives the data and address bus during data transfer. So, it is purely a physical address.

    What Are Your Thoughts On Declarative Vs Imperative Paradigms Such As Functional And Object

    Programming paradigm is a broad categorization for languages as either declarative or imperative. However, it is useful to consider these general programming styles rather than concrete language directives. While certain approaches may be cumbersome in some, there are many that are not as rigid. Languages such as JavaScript and Java allow either approach to be taken, even if they lend themselves toward one approach over another.

    With questions like this, employers want to gauge your familiarity with more abstract concepts in software engineering. There are many approaches for writing high-quality, maintainable software. Intelligently implementing a programming paradigm requires knowing at least some of the benefits and trade-offs of each.

    As with any subjective question, there can be strong opinions on the topic. While answers should be stated confidently and with supporting experiences, it is very easy to slip into speaking negatively about your less-favored approach. The interviewer could have the opposite opinion, creating avoidable tension. Focusing on objective obstacles you face with the approach will avoid the situation and potentially open a friendly dialogue on the pros and cons of each.
