Suppose that in an interview an applicant who have received a master's in computer engineering wants to say that in addition to the theoretical lessons and studies in the university, he also have done practical projects, such as programming a software, and have developed some skills while doing these projects. In the first place, I thought that the following sentence is a good one and practical is a suitable adjective here:
In addition to theoretical knowledge, I have also developed my practical skills.
But I saw this page where it has been said that practical skill can be anything, like replacing tire, using Microsoft word, and cooking. It made me doubtful if it is a good adjective here because it may be too general. Employer may think "what does replacing tires and cooking have to do with this programming job position?"
