home care nurse? means private nurse taking care of a patient on their home? if it is....it's not a good offer.....errrrrr....just my opinion, it is still up to you. and the QR3,100 salary is a little bit low if you already have a family. for a single person, it is fine as you are just starting to gain experience.
for the question of the company really exists....I don't have an idea as it easy to named business with "Doha" in it just to look it is a good one. we'll wait for the others...
