Currently 3 years over Bayt, applied more than 300 jobs. Not even one interview. Is this platform really beneficial ?

In my personal opinion simply try to re build your CV by Bayt professional CV writer then judge! 

Moreover, i would say that Bayt company has to review the history of each customer ( job seekers like us ) every year to evaluate why we did not win one job over the total applications we have sent a long one year.

Thanks
