What Information Can Be Included In A Test Plan
This is a question that tests your basic knowledge about best practices in software testing. Interviewers may ask this and observe your reaction. Be sure to analyse the question and formulate a concise but specific answer that would show them that you’re an experienced and qualified candidate.
Example:’The information I typically choose to include in the test plan depends on the type of test that the team is performing. However, the main elements of every plan are strategy, objectives and criteria. Based on the individual objectives for the test, I develop a strategy to reach those objectives. I also use the criteria to see how the software performs under different circumstances.’
Behavioral/culture Fit Software Engineering Interview Questions
Q1. Tell me about a tough software development problem and how you solved it.
Give a brief description. Make the assumption the other person doesnt know any specialized vocabulary or industry-specific challenges. You can also ask the interviewer about their familiarity with the topic youre about to describe and mold your answer based on the other persons level of context .
Q2. Do you have any personal projects? Tell me about them.
Sometimes its hard to settle on an idea for a project. If you have that problem, start by making a replica of a different application with a different tech stack or something. This will get your brain pumping and eventually youll come up with something youd rather do. The key isnt coming up with a great idea. The key is to get started on something.
After youve worked on your replica for a while, you might notice some shortcomings in the app that you can fix. Or you might realize that you dont want to make this replica anymore and you start on something else. The purpose of replicating an existing app isnt to really make the replica. The purpose is to get you started on something so that youll find what you really want to do.
Q3. Explain the concept of cloud computing to my older mother.
Q4. Have you ever disagreed with your boss or manager? What did you do?
Q5. Why do you want to work at ? Have you used our products?

Technical Skills Based Questions To Ask A Senior Developer
You will need to ask your developer team for advice when it comes to asking questions related to technical skills during an interview. This is why there is often a behavioral interview and a separate technical interview. Here are some Senior developer interview question examples:
- Are you still writing code? Do you love it?
- What are the pros and cons of cloud systems?
- For a fintech application, what security concerns would you have? And how would you address them?
- What technologies, programming languages, and frameworks would you use if you had to develop a project from scratch in only one month?
- You have just been put in charge of a legacy code project which is difficult to maintain what would you plan to improve in order to make the project easier to maintain in the long term?
Remember to also tailor interview questions to suit the specific technologies of your company. So for instance, ask a senior Java developer a specifically tailored Java interview question. Likewise, ask Android developers about the technologies they would use to create a new Android app. If your company uses a specific programming language, it is good to know that your senior programmer candidate is experienced in that area.

What Are Your Thoughts On Software Testing
Testing is an extremely important component of the software development life cycle because it ensures the quality of the software before it is deployed to users. Approaches to testing range from manually testing the application to writing test suites for individual code modules, or unit testing. Within these approaches, there are many schools of thought. For example, unit tests may be written in a strict test-driven process where failing tests are written before any business logic, aiming for 100% of the code to be exercised. There are other approaches that enumerate particularly complex or sensitive code and write a test for those as opposed to every line.
In fact, the point is even debated amongst the writers of The Manifesto for Agile Software Development, which arguably popularized testing as a standard part of the software development process. In the 2015 talk, Agile is Dead, co-author Pragmatic Dave Thomas stated, I mostly dont test. This is in sharp contrast with other co-authors such as Martin Fowler and Kent Beck who largely advocate for a test-driven approach.
You should have informed opinions on why you favor one approach over another. It will demonstrate that you are aware of the range of methodologies and have made a choice based on sound reasoning. Similar to speaking about Agile software development, negative statements should be avoided in general.

Do You Have Previous Experience In Software Testing
This is one of the most common questions that interviewers may ask during your interview. It helps them understand your background and how your career has looked like before you’ve decided to apply to their company. In your answer, you can briefly explain your journey as a tester to them, list some of your previous duties and responsibilities and describe your past projects and processes.
Example:’This month marks five years since I first started working as a software tester. Since then, I’ve done both manual and automatic testing. In my previous role, I focused on performance and functionality, which I consider my specialisation. I’ve also had the chance to work with stress testing processes a lot.’
What Do You Understand About Fuzz Testing What Are The Types Of Bugs Detected By Fuzz Testing
Fuzz Testing is a software testing technique that utilizes erroneous, unexpected, or random data as input and then looks for exceptions like crashes and memory leaks. It’s a type of automated testing that’s used to define system testing techniques that use a randomized or dispersed approach. During fuzz testing, a system or software program may have a variety of data input problems or glitches.
Following are the different phases of Fuzz Testing:
Following are the different types of bugs detected by fuzz testing:
- Failures in assertions and memory leaks – This practice is often employed in large applications where defects compromise memory safety, which is a serious flaw.
- Invalid data – Fuzzers are used in fuzz testing to generate faulty input that is used to test error-handling methods, which is critical for software that does not have control over its input. Simple fuzzing is a technique for automating negative testing.
- Correctness bugs – Some forms of “correctness” flaws can also be detected using fuzzing. For example, a corrupted database, inadequate search results, and so on.

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

Given A Set Of Numbers
Put all the numbers from the array into a hash. So, keys will be the number and values of the keys be . This will take one pass. O.Now, foreach key ‘k’, with value ‘v’: if k == v: there is a match and that is your pair.this will take another O pass totale O ~ OLess
Easiest way to do it. Written in python. If you consider the easiest case, when our summed value is 0, the pairs will look like-50 + 50-49 + 49-48 + 48etc….etc… So what I do is generalize the situation to be able to shift this k value around. I also allow us to change our minimums and maximums. This solution assumes pairs are commutative, i.e. is the same as .Once you have the boundaries that you need to work with, you just march in towards k / 2. This solution runs in O time.def pairs: if k & gt = 0: x = maximum y = k – maximum else: x = k + maximum y = minimum while x & gt = k / 2 and y & lt = k / 2: print str + ” , ” + str + ” = ” + str x = x – 1 y = y + 1Less
here is my solution using hash table that runs in O =& gt O: public static String findNums catch } int num2 int num1 for } //System.out.println) return “No numbers exist” }Less

Role And Responsibilities Of Test Engineers
So what exactly do test engineers do? In the simplest terms, test engineers create and run quality assurance operations on products or systems to confirm that they function properly and meet the needs of the final audience. Test engineers also run case-scenarios to determine what problems could arise during the use of the product or system and how these issues can be addressed. The goal is to iron out as many bugs as possible, resulting in a high-quality commodity.
Specific job responsibilities of test engineers may include:
- Testing various aspects of the product or system, such as function, performance, regression, and service
- Designing test environments, test plans, test cases and usage scenarios, and executing these operations
- Providing feedback on useability and serviceability
Senior test engineer duties include:
- Developing tests and designing hardware or software to execute said tests
- Verifying and validating new tests, test systems, and solutions
- Performing automated and manual tests and interpreting test results
- Creating, updating, and communicating documentation of tests performed
- Providing technical expertise and design input
Technical understanding and experience are requisites of this position, but test engineers must have other soft skills to perform their roles successfully. These include:
