Differentiate Black Box Testing From White Box Testing
Here, your knowledge about black box and white box testing is tested. The interviewer wants to know whether you can differentiate the two.
Tip #1: Define black box and white box testing
Tip #2: Differentiate the two types of testing
Sample Answer
White box testing seeks to test an application with an understanding of its internal structure as well as code implementation. This type of testing is done by the developer who wrote the code and is conducted in the form of unit tests.
On the other hand, black-box testing regards testing an application without knowing its code implementation or internal structure. Here, testers are only concerned about software functionality rather than the code execution or data blow.

Which Aspects Do You Pay Attention To When Reviewing A Code Developed By Your Team
The interviewer wants to know the approach you take to review codes.
Tip #1: Describe the aspects you focus on in your code review
Tip #2: Show that you are competent in reviewing codes
Sample Answer
I begin by looking at the functionality, security, and readability of the code. Here, I ask whether the code is simple, or bloated, cluttered, and inefficient. Then, I assess how many lines of unnecessary codes should be removed or re-written. I also find out whether there is any weakness that might result in vulnerabilities. Besides, I check and confirm that the code has met the standards and regulatory requirements.

Candidates spend a day at one of the Amazon offices for these rounds and meet with interviewers across company levels, i.e., hiring managers, team members, managers, and senior executives.Out of all onsite interviews, 3-4 will mainly focus on coding questions, i.e., data structures & algorithms, computer science fundamentals, and system design questions.

What Happens Behind The Scenes
Your recruiter is leading the process and taking you from one stage to the next. Here’s what happens at each of the stages described above:
- After the phone screens, your recruiter decides to move you to the onsite or not, depending on how well you’ve done up to that point
- After the onsite, each interviewer files their notes into the internal system, grades you and makes a hiring recommendation
- The “Debrief” brings all your interviewers together and is led by the Bar Raiser, who is usually the most experienced interviewer and is also not part of the hiring team. The Bar Raiser will try to guide the group towards a hiring decision. It’s rare, but they can also veto hiring even if all other interviewers want to hire you.
- You get an offer. If everything goes well, the recruiter will then give you an offer, usually within a week of the onsite but it can sometimes take longer
It’s also important to note that recruiters and people who refer you have little influence on the overall process. They can help you get an interview at the beginning, but that’s about it.

Have You Ever Failed As A Software Development Manager What Do You Learn
Everyone can fail at some point but the important thing is to learn from failures. The interviewer tests whether you learn from your mistakes.
Tip #1: Describe a failure that you experienced
Tip #2: State the lesson you learned
Sample Answer
During my last assignment, I got a new client who wanted a particular software product for his business. I promised the client that the software would be ready in a month. When the development process began, we realized that some modules were a bit complex to develop and consequently they took time. After a month, the software wasnt ready yet. I realized I had underestimated the project completion time. The client got annoyed by the failed promise. But I reassured him that we were on course. Eventually, we deliver a great product. I learned that it is essential to assess the requirements of a project carefully to know exactly how much time will be needed to deliver it.
Do You Consider Unit Testing Essential Or A Waste Of Time
The interviewer wants to understand how you regard unit testing
Tip #1: Describe your understanding of the unit testing
Tip #2: Show whether unit testing is vital or a time-wasting process

Unit testing is considered by most professionals in the industry as a best practice in software development and code maintenance. It is part of the overall testing strategy.
