Am I making a bad career decision?

Hello all,

Context:

I am currently a student in my final year doing a BS in Computer Science. The NFQ level is 7.

I just finished an internship at a FAANG+ company in Dublin and got a return offer for a full time position as a software engineer.

Today I was speaking with a lecturer and they were saying to me I should go on and do the extra year to get the NFQ level 8. I told them that was my plan initially but over the summer I was doing an internship and they are giving me a return offer and are happy to take me with the level 7. My lecturer then went on to tell me I was making a bad idea and it will limit the companies I can get a job in after. This has screwed with my head totally.

Just to mention that the full time offer was for July 2025 and would not have been around the following year.

Question:

Am I making a bad decision accepting the full time offer? Should I have stayed on to get the level 8?
