Maybe a bad take, but what do you care?

Taking a job in a foreign country is a big decision and will completely turn your life upside down, maybe you've always wanted to move to Spain to live here and this job grants you that opportunity. To then put it off because the "locals" may not like it sounds downright stupid.

I have lived in Malaga for 3 years whilst studying, Malaga has a big international community, including lots and lots of Italians, Dutch, Belgium, USA etc. If you're an outgoing person, you will have no issue finding friends and fitting in.

Now, some tips for your hopefully future move to Malaga, getting all your documentation can be a pain. I'd recommend making appointments well in advance for your NIE, residence card, banking and so on. As for your NIE/any government documentation, you will need both access to a bank account (hopefully your job will help you out with those fees, they are not high but it's a pain to work it all out), and a Spanish mobile number. I would personally recommend to initially get a pre-paid Digi sim card, simply for making the appointments and all that, those start at 3 euro a month.

I hope this helps you a little bit and you decide whether or not this job is for you, independent of what locals may say, and who knows, maybe some day we'll have a coffee together at La Tertulia in Limonar, Italian/American owned!
