jobs & housing question...

Things definitely slow down during Ramadan, but there could be other reasons why the positions have been put on hold.

There are strict limits on the number of people you can bring with you to live in Saudi Arabia.

Expatriates cannot typically bring parents as dependents, but of course they can visit. Your housing would be based on the number of dependents the company certifies as meeting HR policies, which in your case looks like wife and 3 kids assuming they all live with you and there are no complicated family dynamics at play. That would likely lead to a 3BR. Depending on when you come, they would assess what's available at the time of your family's arrival. You might end up in a local compound in a 3 BR villa. Depending on availability, it's possible you could move straight into camp, but still likely a 3 BR, depending on the grade code you're brought in at.

There have been many housing changes over the past year or so. Again, depending on your position, GC and passport, you could end up being offered on camp housing, local community compound housing, or a housing allowance, and you might have to find housing and schooling outside of camp. It really does depend on a number of various factors.

The specific housing you get really does depend on whatever is available the moment your family gets approved for their visas and they have confirmed travel plans. Then they look to see what is available that matches your GC and dependent requirements at that time and begin the housing assignment process.
