Dude I’m Mexican so I speak some Spanish but I’m not quite understand the question
It should be hablé since if it talking about someone else. If it were to be you, however, the sentence would be “Yo hablo con Juan.” Comprende?
The sentence says “ I never had to accept this job before.” Trabajo is a noun. If you are trying to say, “ I never had to work before ”, then It would be “trabajar” because it is after the verb “había”.
