I am a third year electronic engineering undergraduate student. I'd like to gain some practical experience in the workplace through vacation work (be it paid or even unpaid if the company cannot offer remuneration).
From past experience and searches I have noticed that companies in my country do not generally advertise such opportunities on jobseeking websites.
My question is therefore what is the appropriate way to approach companies for student vacation work (email, telephone, direct visit?) and is it acceptable to do so?
How do companies, especially in the engineering and software fields, feel about employment of students over vacation periods?
