These types of interviews are very specific. These interviews test your technical knowledge and analytical skills at the same time. In these interviews generally questions are related to the core expertise of job profile. They are interested whether you are suitable candidate of the current requirement of the job or not. Regardless, technical interviews of all types often consist of brainteasers, riddles and practical questions designed to measure your logic, reasoning, creative thinking, and problem-solving skills. 

Some of the common points need to be remembered during interview:

• Try to provide the point to point answer
• If you do not know the answer than politely say “I do not know the answer or I do not remember the answer”. Do not try to confuse the interviewer.
• When you have been asked a question, please try to give a approach to answer that, it is the approach which is important rather than answer.
• Prepared basics very well, generally in technical interviews only basics are asked
• Prepared all projects done by you. The enhancement which can be made in your project etc. These are very common questions in technical interviews.
