Internship in leveraged finance vs full time job in trading

I have just completed an MSc Finance degree at a top 3 school in the UK and have been offered an 11 month internship in leveraged finance at a tier 2 bank. I also have a final round interview for a full-time equity trading role at another tier 2 bank where I used to work in middle office.

I am facing a huge dilemma. On one hand, leveraged finance is definitely a career path that I want to go down, given my interest in PE, the chance to gain good modelling skills and exit opportunities. However, the role is not permanent and pays considerably lower than a BB. The trading role on the other hand is permanent, pays a lot more than the internship and I really liked the team and know the company well. But it is not really the career path I want.

Should I focus on my long-term career plans instead of short term financial and job security?

Thanks!
