What the interviewer wants to know
The purpose of technical interview questions is to determine whether you possess the hard technical skills required to perform the job well. Interviewers for technical roles often care about your thought process. In some cases, they may be more interested in how you approach a particular situation than the exact solution you decide on. During the job interview, provide examples of your skills as they apply to the position you are applying for. Attempting to match your qualifications to the job description will make it easier to respond. Depending on the job you are applying for, you may also be asked to answer the following questions:
- Skills and experience
- Certifications
- Competencies
- Processes
- Systems, languages, and tools
Top 50 Technical Interview Questions
When interviewing in the tech industry, expect to be asked questions about your training and certifications, as well as behavioral, situational, and questions about your knowledge of technology and design tools, along with questions about your habits, work, and processes.
Interview Questions About Your Education
What they want to know: While many tech professionals are self-taught, some may have completed at least a secondary education from technical colleges or universities. Be sure to mention all the technical certifications you have earned. What are your technical certifications? How has your education prepared you for this job? What do you do to maintain your technical certifications? How do you assess your core capabilities for this role? What are your strengths and weaknesses in IT?

What are the necessary elements for a successful team and why? What percentage of your time do you spend on unit testing? What do you expect in the solution documentation provided to you?

How to Prepare for the Interview
Learn as much as possible about the company and the department you are applying to before you walk into the interview. Candidates who can confidently answer questions about the company are much more likely to move forward to the second interview than those who fail to do their homework. Prepare answers for standard interview questions as well as technical questions. Employers will care about how you have overcome challenges in the past, as well as whether you will fit into their organizational culture. They will also want to know about your short-term and long-term career plans to determine if you are likely to stay with their company. Expect some tough questions. Some hiring managers may ask probing questions to see if candidates are able to think on their feet.
