Software engineering internship questions about experience and background

Software engineering professionals often have previous education, job experiences or industry certifications that qualify them for their roles. As an intern, you may be in the process of earning a degree or looking to expand your professional experiences after earning your degree. Therefore, hiring managers understand that you have limited professional work experience and typically focus on your education and other related topics in the questioning. Here are 10 examples:

  • What made you want to pursue a career in software engineering?

  • Can you tell me more about your college major? what types of courses have you taken that relate to software engineering?

  • Have you completed software engineering internships in the past?

  • What software engineering project are you most proud of? Can you tell me more about the creation process?

  • What examples can you provide from your previous experiences that demonstrate your ability to test and debug software?

  • Have you ever had to complete a group programming project? What was the experience, like and how did you work as a team?

  • What programming languages have you used to create a website, versus a mobile application?

  • Do you have experience referencing coding libraries to complete updates on software systems? If so, what is your process like?

  • Have you ever needed to organize CSS files? If so, what's one or more methods you've used to do this?

Software engineering internship interview questions with sample answers

Review these additional software engineering internship questions and sample answers to learn how to respond in a professional manner:

An entry-level software engineer claims to have found an error in your code, but you can't identify it. What do you do as an intern?

An interviewer asks this question to see whether you would feel comfortable asking questions to employees about your work. Ultimately, they want to know how you'll interact with their employees and how you'll demonstrate respect while advocating for clarity on feedback. Your answer should demonstrate your professional attitude and desire to learn from experienced professionals.

Example: "The first thing I would do is go over the code one more time to make sure I couldn't find anything. If I still don't find it, I would go to them and ask if they could assist me when they haved a free moment. Because I have a short professional history in software engineering, I want to learn all I can from the experienced software engineers around me."

Can you tell me the difference between a two-tier system and a three-tier system? What types of software would you use for each?

During your internship, you might have the opportunity to create a variety of software systems and applications. By asking this question, an interviewer wants to learn more about your knowledge of software systems, how they differ from one another and what types of applications you'd use them for. Your answer should clearly define and differentiate two-tier systems from three-tier systems, but it should also highlight examples of each.

Example: "The difference between a two-tier system and a three-tier system is that a two-tier system is comprised of a client tier and a database tier. In contrast, a three-tier system is comprised of a client tier, business tier and data tier. You would use a two-tier system for software like contact management software. In contrast, you would use a three-tier system for software like database management systems."

You receive one assignment that requires black box testing and another assignment that requires white box testing. What does this mean?

Interviewers use this question to find out more about your technical knowledge and whether you'd be able to understand software engineering terms to complete daily work tasks. Your response should include a definition of each type of software testing and how they'd translate into your job duties.

Example: "If asked to complete an assignment that requires black box testing, this means that I am testing a system that I didn't design myself. In contrasted if asked to complete an assignment that requires white box testing, this means that I am testing a system that I did design myself."

I ask you to create a microservice app. Can you tell me what this would mean?

As a software engineering intern, you'll likely encounter a variety of projects that vary in difficulty. When asking this question, interviewers want to determine your range of experience creating software applications and your knowledge of terms. Your answer should define a microservice app clearly and concisely.

Example: "To create a microservice app would mean to create an application that's comprised of multiple services (businesses). These services aren't connected to each other, but provide users the option of purchasing goods, scheduling appointments or placing delivery orders. Further, software engineers use microservice apps to ensure high performance and speed for app users."

Types of internship interviews

Here are the types of internship interviews you might encounter when meeting with employers for a software engineer intern interview:

  • Phone interview: Employers typically use phone interviews as a part of the screening process to provide internship candidates with information about the position and to gauge their personality. A good phone interview could determine whether an employer asks to meet a candidate in-person.

  • Previous experience interview: This type of interview focuses specifically on a candidate's prior professional experiences, coursework or software engineering projects.

  • Video interview: Video interviews or virtual interviews are those that take place using video chat software. Employers may use a video interview format if a candidate currently lives outside of a reasonable traveling distance or if they offer a remote internship experience.

  • In-person interview: If an employer wants to learn more about an intern candidate after a pre-screening, they contact them to schedule a one-on-one interview with them at their office location.

  • Programming knowledge interview: Interviewers may dedicate entire interviews to asking candidates about their knowledge of data algorithms, coding libraries and other programming concepts they need to be able to use during a software engineering internship.

  • Panel interview: A panel interview is usually an in-person style interview where multiple company employees interview one candidate by taking turns asking questions.

  • Group interview: When an employer looks to hire multiple interns, they might use a group interview format to survey candidates in a timely manner. group interviews consist of a panel-style discussion where one or more interviewers ask each candidate the same question. Depending on the employer's preferences, they can also conduct individual interviews during this time.

  • Coding language skill-based interview: When interviewing for a software engineering internship, an interviewer might ask to meet with you to learn more about the coding languages you understand. During these interviews, you might have to complete a coding test or complete a small project to demonstrate your skill level.
