Personal Experience:  I live in Jeddah so I had to fly to Riyadh and submit my application in person. It cannot be done by a third party because they need to take your fingerprint. Within 2 days of submitting my application, I received a call from the embassy in Riyadh for an interview. I had to fly again to Riyadh for the interview and my visa was approved the day after the interview! MY FIRST SCHENGEN VISA AFTER SEVERAL VISA REFUSALS!

UPDATE: They have opened a bls center in Jeddah.
