Top Product Test Engineer Interview Questions & How to Answer

Here are three top product test engineer interview questions and how to answer them:

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

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: How do you go about learning a new product?

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

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.

Product Test Engineer was asked...May 15, 2014

Given an array of 10 numbers, all 0 or 1, write code to turn the 0's to -600 and the 1's to 600 without using any if/then or switch statements.

3 Answers

res[i] = {(arr[i] * 600) + (~arr[i] * -600)}

Alternatively, x = arr[i] << 31 return ( x ^ -600); //assuming x and -600 to be represented in 32 bit signed format and '^' as exor Less

result[i] = arr[i]*1200 - 600

Texas Instruments

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 )

2 Answers

I was able to answer around 75-80 % of the questions. I knew my opamps, circuits, lpf, and somewhat remembered stats stuff (occasionally said I didnt know things), the coding question i admitted not knowing what they were talking about. It wasnt bad, just very intense, got an offer 2 days later Less

The key in these questions is to cover the fundamentals, and be ready for the back-and-forth with the interviewer. Might be worth doing a mock interview with one of the Texas Instruments or ex-Texas Instruments Product Test Engineer experts on Prepfully? They give real-world practice and guidance, which is pretty helpful. prepfully.com/practice-interviews Less

Texas Instruments

Describe a time your were in a team environment and the team failed to meet a task. What did you do? Was the problem resolved afterwards?

1 Answers

It's essential to demonstrate that you can really go deep... there are plenty of followup questions and (sometimes tangential) angles to explore. There's a lot of Product Test Engineer experts who've worked at Texas Instruments, who provide this sort of practice through mock interviews. There's a whole list of them curated on Prepfully. prepfully.com/practice-interviews Less

Microchip Technology

If you have an IC with a maximum temperature rating of 75C, a junction to ambient thermal resistance of 50C/Watt, and a power dissipation of 1W during normal operation, will the chip be able to function in room temperature?

1 Answers

Probably not. Room temperature is about 25C, so adding that to the 50C from the power dissipation, the temperature would be 75C. The chip would probably be damaged. Less

Microchip Technology

If you have a "black box" circuit, and your options of what's inside is a constant voltage source (CVS) or a constant current source (CCS), what kind of tests can you do to determine what's in the box?

1 Answers

Apply a load. Measure the voltage and current. Change the load (either higher or lower, but preferably higher). Repeat the measurements. If the voltage is the same, then it's a CVS circuit. If the current is the same, then it's a CCS circuit. Less
