Understanding how to answer information technology (IT) interview questions is essential for securing a job in the field. In trying to get to know you better, hiring managers for IT positions tend to ask three types of interview questions. In this article, you’ll learn about the types of questions interviewers ask, see examples of 21 common IT interview questions and learn how to answer them.
1. Tell me about yourself.
“I recently graduated with a degree in computer science and am really excited about the prospect of this position. I have interned with a few mid-size companies and was able to work closely with their mobile developers. I also have a lot of experience with online code repositories, and I love to contribute as much as I can.”
2. How would people describe you?
“I would say that people would describe me as a good communicator because I’m always able to articulate people’s needs, whether it be clients or my teammates. I’m able to quickly pick up on subtle hints and nonverbal clues, and I believe this has helped contribute to my success.”
3. Which is your most significant accomplishment?
“When I first started at my internship, the onboarding process wasn’t very thorough, and the initial training for developers left a lot to be desired. After sharing my concerns with my trainer, I was able to help develop better resources for new employees as well as restructure the program entirely. I feel like this showed both my initiative and my problem-solving abilities.”
4. What is your greatest strength?
“I’m highly motivated and am extremely passionate about developing. I am known for completing projects ahead of deadlines, and I feel this is especially important when things are constantly evolving and changing. I take initiative and am always coming up with various ways to solve a problem without needing to wait for direction. I also am always up-to-date with the newest trends and am willing to try the latest thing.”
5. What is your greatest weakness?
“I would say my biggest weakness is that I’m a recent graduate and don’t have a lot of work experience, but I’m a fast-learner and am highly adaptable. I’m up-to-speed with the latest programming trends and have a fresh perspective. I know I have enthusiasm for the work, and I will bring my strong work ethic and commitment every day.”
6. What are your preferred programming languages and why?
“My preferred programming language is Python because it’s easy for a beginner to pick up and it has a lot of excellent libraries. The support libraries greatly reduce time spent on coding, and I find it helps me be creative yet efficient.”
7. What is a class? What is a super-class?
“A class defines the characteristics of a certain type of object such as which messages they will respond to and what form of response they will take. On the other hand, a super-class is the basis of the class under consideration.”
8. What is a default constructor? What is a conversion constructor?
“A default constructor either has no arguments, or all of the arguments have default argument values. A conversion constructor accepts one argument of a different type and uses this as a way to infer conversion rules for a class.”
9. What is the difference between C and C++ ? Would you prefer to use one over the other?
“C++ supports the object-oriented programming paradigm while C is based on structured programming. I prefer C++ due to its object-oriented nature but also the fact that almost anything can be built using it.”
10. What is multiple inheritance? What are its advantages and disadvantages?
“Multiple inheritance is the process where a subclass can be derived from more than one super-class. Its advantage is that a class can inherit the functionality of more than one base class, but its disadvantage is that it can lead to a lot of confusion when two base classes implement a method with the same name.”
