Programming interview questions assess language proficiency, experience, application development, teamwork, stress handling, and OOP knowledge. Employers may ask to see code and demos, and inquire about self-taught programming. Framework and operating system-specific questions may also be asked. Web programmers may face additional questions about web standards.
Common programming interview questions are usually designed to find out what specific language or languages the interviewee knows, how much experience he or she has programming in those languages, what kind of applications he or she has developed in them, whether he or she has ever worked as a member of a team of programmers, and if so, what was your role on the team. If the languages support object-oriented programming (OOP), the interviewer can ask if the interviewee is proficient in object-oriented programming. Other programming interview questions a candidate might expect may concern the model-view-controller (MVC) pattern and frameworks.
Programming interview questions may vary, depending on the specific programming language(s) the potential employer requires knowledge of, the type of application that will need to be developed, and the type of business operation of the company. Many programming jobs in small businesses or organizations require developing applications for internal use only, but others require coding the programs to be used by customers. Programmers who design software to meet the business needs of the company’s customers tend to work under more pressure than those who code applications to be used strictly by other employees, so they may be asked how well they work under stress and how well they can meet deadlines.
It’s not uncommon for programming interview questions to prompt a potential employer to ask to see code for an actual application written by the candidate. The interviewer may even want to see a demo of the software, which is almost always possible with the widespread use of laptop personal computers. Applications that indicate that a candidate is a self-taught programmer will likely prompt programming interview questions about how the knowledge was acquired, over what time period, and whether there are any users of software written by the candidate that can vouch for its usefulness. Candidates who are not proficient in object-oriented programming but who are competent in procedural coding can be asked if they have at least some familiarity with OOP concepts or if they consider themselves to be a fast learner.
Most programming interview questions related to the use of frameworks almost always delve into the specific choice framework used in the company. Although somewhat rare, programming interview questions for a C or C++ developer may include questions about their ability to write programs for certain operating systems, because a good number of C and C++ developers code software strictly for a specific operating system. Candidates for a web programmer position should be ready to answer questions that candidates for software developer positions might not be asked, such as questions about the following web standards.
