You may think that now you're at university the time for STEM summer camps, workshops, masterclasses and taster days are far behind you, but there are still a few available to you, such as the European Space Camp or volunteering at the British Science Festival. These could help you get just that little bit more experience you need to get an internship or even job offer. At the very least they should be a fun experience.
Please note, this website will focus on smaller, less well known opportunities where possible - and I will not be posting internship opportunities since there are simply far too many to list and are usually fairly simple to find on employers' websites (if you are searching for internships, have a look at companies/ organisations in fields you are interested in and find their careers page).
