Honestly, some prefer Filipinos because they are fast learners and hardworkings. Based on most employers I have talked to. If employers are hindi, Urdu, kerala, they prefer on the same nationality. Language barriers is really difficult working here in middle east. Other employers prefer bilingual (Arabic/English) . Of course I understand because it would be much easier to communicate if we soeak the same language. So it would be an advantage to job seekers if they speak multi language also read and write.
For experience, you can ask for a high salary or you know your worth, they know your worth. If they know you are fresher, entry level or have less experience on the job you are applying, they will offer bargain salary which is very disgusting sometimes. Even you are skilled, some would offer a very very low salary 150bd or 180bd for a highly skilled applicant. Thats it. No allowances or others. All in. When they know you are visit visa, they will chop down your salary even more.
Applying job is so hard here in Bahrain IF you are seeking for HIGH salary 250bd above for skilled applicants. There are bunch of jobs if you are okay with 180bd below all in. Some offer 150-180bd plus accomodation allowance and transport. Thats it. You will be lucky enough to find an employer who can offer you high salary. Target big companies. Well stablished companies. They will offer better benefits almost same as local bahrainis salary and benefits. Otherwise, there is always a discrimination. When you are not arab nor Bahraini, your working hours will be different. 9hrs to 10hrs. No holiday off. So beware to these type of employers.
For interviews, some will jusy do the interview thru phone. So stay alert always when you are sending resumes. They may call on any day on any time. They can even just hire you thru phone when they like your cv and portfolio. Whatsapp here in Bahrain is necessary. So better have a whatsapp account. Other employers and companies just post their numbers in whatsapp for you to contact them. Keep looking for other jobs and don't rely to what employers say verbally and leave you hanging if they don't contact you after successful interviews or hired verbally. Until you see in your eyes the contract offer letter then consider it sealed and your working visa is being processed.
Bahrain Expatriates website have bunch of job offers daily. It will be a big help on job hunting there. As well facebook groups in Bahrain, Linked and indeed. I find these apps very useful and important in job hunting.
If you are not arab, Be wise in dealing salary! Goodluck.
