If a person achieves something, such as getting a good job, keeping in mind that it wouldn't have been possible without the Will of Allah of course. Does the individual get any form of credit, because he took the means to work hard for it. So he feels good about himself, or someone praise him for it

Yes, insha'Allah, Tabaraka wa ta'ala. So he increases in hamd to Allah subhanahu wa ta'ala that He bestowed all of this upon him, and He gave him the means, the energy, the health, and so on, in order to do so. This is part of developing your character. Being serious, sincere to Allah, depending on Allah, taking the necessary means, and being responsible shapes your character as well. And alhamdulillah, always praise Allah subhanahu wa ta'ala, even for rectification in your character, good traits in your character, and so on.
