In a job application process on bayt.com , when my ranking is 1 out of 256 how come this position is closed without contacting me ?

I'll suggest you to go back to the application page and check whether the following opening is for the people who are residing in that country only or outside of it too, and sometimes more often than not vacancies are filled through internal referral process !!!

You can contact with BAYT. They can give u a better answer than us.

As it is happening myself, can you contact with BAYT? They are the best source of answers.

For such cases you can contact bayt office
