Dart Interview Questions for Developers

Use our engineer-created questions to interview and hire the most qualified Dart developers for your organization.

This Google-developed language was primarily created for building web, server-side, and mobile applications with an emphasis on performance, ease of use, and scalability.

Dart is a strongly typed language with a sound type system, which helps to catch potential errors during development. It also features automatic memory management through garbage collection, which simplifies memory handling for developers.

In order to evaluate the skill level of developers in Dart during programming interviews, we provide a set of hands-on coding exercises and interview questions below. Additionally, we have developed a range of suggested methods to ensure that your interview inquiries accurately measure the candidates’ Dart capabilities.

Dart example question

Help us design a parking lot app

Hey candidate! Welcome to your interview. Boilerplate is provided. Feel free to change the code as you see fit. To run the code at any time, please hit the run button located in the top left corner.

Goals: Design a parking lot using object-oriented principles

Here are a few methods that you should be able to run:

  • Tell us how many spots are remaining
  • Tell us how many total spots are in the parking lot
  • Tell us when the parking lot is full
  • Tell us when the parking lot is empty
  • Tell us when certain spots are full e.g. when all motorcycle spots are taken
  • Tell us how many spots vans are taking up

Assumptions:

  • The parking lot can hold motorcycles, cars and vans
  • The parking lot has motorcycle spots, car spots and large spots
  • A motorcycle can park in any spot
  • A car can park in a single compact spot, or a regular spot
  • A van can park, but it will take up 3 regular spots
  • These are just a few assumptions. Feel free to ask your interviewer about more assumptions as needed

Interview best practices for Dart roles

To conduct effective Dart interviews, it’s crucial to consider various factors, such as the applicants’ experience levels and the specific engineering role they’re seeking. To ensure your Dart interview questions yield the best results, we recommend adhering to these best practices while interacting with candidates:

  • Develop technical questions that mirror real-life scenarios within your organization. This approach will not only engage the candidate but also enable you to more precisely evaluate their fit for your team.
  • Encourage a cooperative atmosphere by allowing candidates to ask questions throughout the interview.
  • If you’re using Dart for mobile development, make sure your candidates have an understanding of mobile dev concepts such as layout design, UI components, navigation, and handling user input.

Moreover, it’s important to follow standard interview practices when executing Dart interviews. This includes adjusting question difficulty based on the applicant’s skill level, providing timely feedback on their application status, and enabling candidates to ask about the assessment or collaborate with you and your team.
