Lesson Wednesday

At the end of every section, we'll take a break from coding to practice interview questions with our partner. These questions will (primarily) revolve around the content we learned in the section, and, much like a "real" interview, some will be more technical than others.

In addition to learning how to implement the new tools, technologies, and concepts, you want to become comfortable talking about them so you can accurately demonstrate and communicate these skills you've learned to potential employers in an interview.

Take turns answering the questions below with your partner.

Technical Interview Questions


  • What is encapsulation? Why is encapsulation so important in object-oriented programming?
  • What is abstraction? How can we use it to help encapsulate our code?
  • What is the difference between public and private methods? When should we use public methods and when should we use private methods?
  • What is separation of concerns? What are some techniques we can use to write well-separated code?
  • What is the difference between static and instance methods? When should we use one or the other?
  • What are the benefits of namespacing our classes?
  • What are getters and setters?
  • Why should we separate out our Main() method into another class?

Stories and Examples


Offering a tangible story or example that highlights your skills usually goes much further in an interview than simply telling your interviewer you're good at something. (i.e.: Telling a story about a time you tracked down a tricky bug versus simply saying "I'm good at problem-solving!").

Review the STAR method, discussed in this lesson on non-technical interviews. Use the STAR method to practice answering non-technical questions with your partner.

Again, if you come up with a story or example you feel good about, jot it down somewhere! It's tough to come up with stories like this in an interview on the spot. Having a few tucked away to review before an interview will be a huge benefit to you later.
