Have most of your jobs been obtained through mainly your own efforts or through a connection?
My mom is one of the most respected physicians in my state, so it has definitely been helpful to throw her name around.
Other than my first job working for my uncle, all on my own.
A combination, usually. One was definitely a connection. But with the others, I consulted people who were helpful in suggesting a person I might work well with (as a grad school mentor), and then as a boss. In both of those cases, though, no one contacted the prospective boss to make a pitch for me; I applied & was evaluated on my own merits. But I probably wouldn't have found them without some guidance.
