Using one's past experience to find a new job

Q: I got my job through the reference of my father's friend. I always doubted the procedure for acquiring a job but under my father's pressure worked for 3 year then I left. I thought that Allah will not be happy with me although I wanted my Allah to provide for me a job by better means. Now I want to know that whether I can use my past experience to find a new job or not?
