Is there any way around applying for summer internships even if you were unsuccessful for the spring days?

Hi Thoiba, yes you can apply for both if you were previously unsuccessful!
However, for clarity, the Spring Days are aimed at Students in their 1st year of a 3-year degree and 2nd year of a 4-year degree. The Summer Internship is aimed at students in their penultimate year.

Are there any summer internships or other opportunities aimed at a 1st year of a 3-year degree?

Yes, our Discover EY programme is open to 1st year students doing a 3-year degree! You can find out more about Discover EY here: https://www.ey.com/en_uk/careers/students/programmes/undergraduates/discover-ey

How many times can someone apply if they've been unsuccessful applying for spring insight week?

However, the applications for Discover EY are closed now, am I right?

You can reapply to any programme 6 months after receiving your email telling you were unsuccessful

Yes we are now closed for this year's Discover EY programme - it depends what year you are currently in if you would be eligible for Discover EY next year or the Summer Internship

Other than the Discover EY programme are there any other opportunities?

Unfortunately not, we do have a lot of online and in person events that you can take part in such as information webinars, office open evenings, and application boot camps. You can look at our upcoming evnets here - https://www.ey.com/en_uk/careers/students/events-and-contacts

Is there any summer internship that is available for master's students in their final year? thank you :)

It would just be the Graduate programme you would be eligible for in your final year of Masters!
