Common Technical Interview Questions

When you are interviewing for an Information Technology (IT) job, you will be asked focused and specific technical questions about your education, skills, certifications, languages and tools you have expertise in.

The best approach when answering is to give specific examples whenever possible. Providing details and experience will tell the interviewer that you have handled projects and situations in the past, deeming you more qualified for the job.

Here are some of the questions you may come across with in an interview. Review this list and prepare your responses based on your qualifications and the nature of the job.

• What are your technical certifications?
• How do you maintain your certifications?
• What development tools have you used?
• Which all programming languages have you worked in?
• How do you handle multiple deadlines?
• How do you troubleshoot IT issues?
• Tell me about the most recent project you worked on. What were your responsibilities?
• Tell me about the project you are most proud of, and what your contribution was.
• What is the biggest IT challenge you have faced and how did you handle it?
• If you know you aren't going to make a project deadline what will you tell your manager and/or the client?

These are just a few, but most common, of the questions that might be asked. They are enough to give you an idea of what to expect during an interview, but do keep in mind that different positions and companies have different requirements, so questions will vary. But your answers should reflect that you are well-experienced and well-informed about the position that they are looking for.

When preparing for a technical interview, you should review basic structures and algorithms within programming. Mastery of these topics will give you necessary knowledge to tackle the problems during the technical interview. Also, review the specific areas for which you're interviewing. E.g. if you're interviewing for a systems programming job, review the differences between threads and processes, OS scheduling algorithms, and memory allocation. Some companies do publish their technical interview questions either on blogs or on their websites. Do spend time in researching on questions asked by a specific employer for the position you are applying for.

If possible, make it a point to carry documentation of any project that you have worked for. This will give the interviewer a better idea about your skills and talents. However, the basic premise of such interview questions is searching for a person who is technically adept as well as professionally good to get along; a managerial attitude is much preferred.

Demonstrate your interest in the position, your drive to excel in the role and the fact that you have done some homework. Ultimately, the more prepared you are for what you will encounter, the more successful you will be.
