The first card is The Hermit reversed, which may indicate that you are not giving adequate attention to the practicalities of the job. You are probably not well focused or not considering all the aspects necessary to find success. You may also be too distracted by other things and care more about appearances than your true efficiency.
The second card is The High Priestess reversed, which could mean that you are not fully heeding the suggestions of those who can help you learn the skills you need to do well at the job. You may even be too proud to admit that you don't know something or are unwilling to learn from others.
The last card is reversed Two of Cups, which can mean that you are making unexpected mistakes and have no awareness of how these things could affect your career. Also, you may not be disciplined enough in your approach to work or the use of your free time, but at the same time you may also be too rigid in your working pattern, thus preventing you from showing creativity and efficiency.
In summary, an overall picture emerges from the cards in which you may not be adequately focused on the skills needed to do well at work, not listen to the suggestions of those who can help you learn, and make unexpected mistakes. To improve these technical skills for the job I recommend that you take the time to focus on the more important aspects of the job and learn from others. Also, you should remember to be disciplined in your approach to work, but at the same time leave room for creative and exploratory moments.
