So your internship is coming to an end. How do you make sure it has been worthwhile and you stay on good terms with the people that gave you the placement? If you do they may even offer you a job in the future.
Ask for feedback
Regardless of how you think your placement went it is useful to find out what you did well and what you did badly. This will ensure that whatever future job you decide to take on, you can take the previous advice into account and make those improvements count wherever you move to.
Ask for more opportunities
Don' be afraid to ask for more future work. A lot of the employees there probably did the same. Just ask if there are any opportunities in future and if they think you did a good enough job, they may consider you. Having already undertaken an internship for them means you've got a nice foot in the door, so there's no cumbersome application process to undertake. Sometimes companies will take on placement students on a part time basis offering to pay them for work they do provide the company with.
Keep in contact
Keep in contact even if they don't keep you on. Ask if they have any jobs going or more placements spare from time to time. Just don't be that annoying person who emails or phones every day. They may move you to their junk pile or block your number.
Ask for contacts
Depending on the company you work with, they may have other contacts in the sector that are looking for interns themselves. Ask for these contacts, you never know, the current placement you're finishing with may pass on a good word.
So finishing an internship doesn't mean finishing for good. There are plenty of opportunities and options after you finish.
