Product Test Engineer Interview Questions

In a product test engineer interview, the interviewer will likely ask questions relating to your technical expertise and problem solving skills. Prepare to go into detail about product design, as the interviewer may assess your ability to master new products. A strong interview would also highlight your ability to be communicative, even under stress.

Top Product Test Engineer Interview Questions & How to Answer

Question 1

Question #1: What are the phases involved in the software testing life cycle?

How to answer
How to answer: With this question, the interviewer is testing your knowledge and is likely seeking a specific answer. To ensure the interviewer of your expertise, mention each of the phases: requirement analysis, test planning, test case development, environment setup, and test cycle closure. Next, clearly define each phase.
Question 2

Question #2: How do you go about learning a new product?

How to answer
How to answer: Try to demonstrate patience, curiosity, and a genuine passion for product design and function. The interviewer may also evaluate how you respond to training. Consider highlighting your willingness to ask questions and use existing resources during your first months on the job.
Question 3

Question #3: Describe a time when a colleague disagreed with your test results.

How to answer
How to answer: You may have proven your competency, however, soft skills are also important. Choose an anecdote that showcases your ability to be communicative. Collaborative problem solving is vital to the role. Aim to demonstrate that you are flexible and can both deliver and accept constructive feedback.

1. Please write a method to normalize a string which represents a file path. For the purposes of this question, normalizing means: • all single dot components of the path must be removed. For example, "foo/./bar" should be normalized to "foo/bar". • all double dots components of the path must be removed, along with their parent directory. For example, "foo/bar/../baz" should be normalized to "foo/baz". That's it. Normally, a path normalization algorithm would do a lot of other stuff, but for this question, don't try any other kind of normalization or transformation of the path. As an example, "foo//bar" should be normalized to "foo//bar" (i.e. a no-op). Use any language you feel comfortable in, we prefer Java, but it’s not required. The method should take in a string (or whatever passes for a string in the language of your choice) and return a string representing the normalized path. Please write code that you feel proud of and would check in to source control in a professional environment. 2. Once you have completed the exercise, please create ten (or more!) test cases you would you use to test the method.

I had two interviews, both at the foodpanda office. -In the first round interviewer asked me about basic JAVA concepts like: difference between overloading and overriding, what is an abstract class, when to use static final? and some simple start programming questions in java. -In the second round, the interviewer aked me to write down the sample code for login page using appium in android, jenkin, github use, framework flow, and projects that I mentioned in my resume. He also asked some questions regarding selenium grid, click , mousehover using selenium, testng. -The overall process took around 1 hour 30 minutes. -Next day HR called me about my confirmation and got an e-mail that I got the job.

Circuit analysis (find equivalent resistance, voltages, your basic circuitry stuff) Op amp stuff (ideal op amp, drawing an inverting opamp, deriving gain) Coding question (I believe it was about private variables) Stats question (draw a Gaussian curve and explain standard deviation and mean) LPF (draw an RC low pass filter and derive gain )

Was interviewed by a Software engineer. It was basically a "highest sum in an array" question disguised in an Oscar health context. Given an array of insulin readings for any given period. Write a function that will return true if an insulin reading is below 10. Array = [90, 92, 93, 91, 104, 102, 102, 106] The input was: Console.log(insulinReadingFunction(Array, 10) == True);
