Your ability to do well in interviews will improve with practice. However, many students avoid the practice and consequently practise using live interviews. The insights from practise can be insightful, but doing it on live interviews seems a waste of a potential job when there are better (free) options.
Interview workshops typically take one of two forms. A talk on interview skills, how to prepare and the pitfalls to avoid. Or face-to-face practice with people in industry who can give you constructive feedback on how you come across. Do both, getting the theory saves having to figure out basic skills using trial and error. Much of it is blindingly obvious once it is pointed out.
Interviews are used primarily to answer the question "can I put this person in my team?", they are assessing whether the team they have in mind will be better or worse off with you in it. Some companies, usually the name brand companies, do technical interviews, but usually so long as you come across as trainable they already have the expertise in house to make you a legendary coder or electronics tech.
This is not implying that technical skills are not important, they are. Technical skills are necessary, but they are also not sufficient for most workplaces.
You have industry people volunteering to provide these workshops for free. They are motivated by seeing good students every year, under-performing at interviews because they have not prepared or practised. You should look to attend several interview workshops while you are studying.
Vic Careers and Employment
Vic Careers workshops
are held all year round and include a wide variety of topics related to helping you find employment.
