Job choice, I need advice

Hello, I've recently finished a master in finance in a public university and passed the CFA level I. I've been looking for jobs a couple of months and now I got 2 job offers.

The first one is a credit analyst. It isn't my dream job because it's basically being in front of a computer analyzing data and calculating risks and forecasts. However they offer me a good contract and it seems a very stable job where most guys work there for many years.

The second one is a job in M&A of a big technological company. It seems a more enjoyable job but they offer me a 1 year internship with no guarantee after that and it seems really hard to develop a career there without contacts. If after 1 year they kick me out it may be difficult to get another job in M&A or IB with only 1 year of experience and because I didn´t go to a prestigious university but maybe I could get a job in an investment firm.

It's important to note that I'm from Spain and we have 20% unemployment and almost 50% youth unemployment so the stability is certainly valuable.

Thanks in advance.
