The interview went well, so he got the job.
Literal
Interview [topic-は] well went [because-ので] he [topic-は] got-employed.
うまく運ぶ ('to go well,' literally 'to carry smoothly') is a fixed expression for things proceeding as desired. ~ので gives the soft causal. 就職できた combines 就職する ('to get a job') with its potential form — 'was able to get employment,' a subtly more careful way than the plain 就職した. Keeps focus on the outcome as an achievement.
