Long time ago the company I helped build hired my friend. I took him in as I knew him very well and knew how hard working person he was. He was hired as junior, he made good 2 years with us and then I helped him to hone his interview skills so he could move to next place (I was leaving too due to unrelated reasons). He is now senior and very successful.
