Does this need my birth details?

The principle needs none; the personal answer does. Birth date, time and city resolve which houses and dasha apply to you, the linked tool does that free.

STRAIGHT ANSWER

Job or business, which suits my chart?

The 10th house and its lord, Saturn (service) versus the 7th and Mercury (trade), and the strength of the lagna lord decide whether a chart earns best on payroll or on its own name.

HOW JYOTISH ANSWERS IT

The real method, not the superstition.

Strong 3rd, 7th and Mercury with a bold lagna lord tilts toward enterprise; a dominant Saturn and a 10th lord tied to the 6th tilts toward service. The running dasha decides the when, a pandit reading your chart weighs them together, this is exactly the kind of question the free ask is for.
