Of cource, in general, immediately looking for a job, with the aim of:
1) Practicing the knowledge (to be maintained).
2) Looking for the (real work) experiences.
3) Earn money (to finance personal & family file).
4) Experience life in real world (must work).
Indeed, there are cases where the decision depends on the condition. For example, in conditions where the parents are quite wealthy (or government offers large scholarships), he/she is still interested in & strong thinking enough, the higher degree will increase the salary, and a lot of teaching & research staff are needed, continuing school (study) is also makes sense and important.
