Many companies like us include ‘technical
interviews’ in their recruitment process to
identify new talent
What is the purpose of the technical
interview?
– To find out how you would put skills, knowledge and
experience into practice
– To show how you would solve a problem
– To gain an insight into your behaviours and how you
would react in a difficult situation
– To find out what questions YOU might ask when faced
with a problem
– To find out how innovative you are; that is, whether
you're able to "think outside the box" to come up with
new solutions rather than using buzz words and jargon
Examples of technical questions and
answers
– Design Engineering – What are the differences between
functional and non-functional prototypes?
Functional prototypes are used for testing whereas nonfunctional prototypes are used for form and fit checking.
Expand on the answers to discuss analysing design flaws,
tooling, etc.
Examples of technical questions and
answers
– Electrical Engineering – Describe the operation of an OpAmp Circuit
Discuss basic operation – differential input consisting of an
inverting and non-inverting input and the op-amp amplifies
the difference between the two.
Discuss aspects such as output voltage, open loop, negative
feedback etc.

Answering Technical Interview
Questions
– Be sure you understand the question; ask for clarification
if necessary.
– Use pictures and diagrams if they will help you explain
the concept.
– If you have to say “I don’t know’ do it in a positive way
e.g. “I don’t know the answer to that question. However
if I had to address that issue in the workplace, here is
what I would do…”

problem-solving abilities as much as your answer!
