Is it permissible to get a job with a reference?

I finished my school with first place and did an internship in a very prestigious institution. In the institution where I did my internship, I received messages of appreciation that I did my job well. Now, the owner of an institution I knew before wants to hire me because I am successful, but I do not have enough knowledge. My English is also not good enough. They told me I could handle these after I got the job. Is it permissible for me to get a job because of my relative when there are people with these skills?
