Season 1, rep level of 20 with a couple of races to go. It seems you'll get an offer from your rival's team if you beat them, regardless of what rep level you are at. Though someone mentioned on another forum they'll drop you at the end of your 2nd season if you can't get your rep level high enough to stay with them.
Luckily despite my poor performance, Massa also had a poor performance in the first few races, meaning I could pick him as my rival... then smashing it at Spa and Monza put me infront of him to get an offer from Ferrari at the end of the Korean Gran Prix.
