Saudia has a selection process really just based on experience, if you meet the experience, can pass the medical and a basic selection simulator then you easily enter the company on a Probation period. During probation they do not have any hesitation to terminate your contract. Having said that if you are a reasonable Captain and you put in the required work then most probably you will pass. The guys I know that did not pass were generally distracted by something during training, this is fatal. Issues such as bringing family over too soon then issues with accommodation or schooling. Another one was getting his saudi driving license then importing his car. The moral really with Saudia is "stay focused".
