Recruiters and HR are human too, if part of their job is done for them then it makes their life easier and your chances of getting the job better.
How do you make their lives easier?
1. get referred by someone the recruiters already know and trust. Easier said than done of course but this basically means your referrer is doing the first round filtering for the recruiter.
2. build a good brand. LinkedIn is probably one of the better options out there, build a good profile, write posts, comment intelligently. When the recruiter does a search on your profile they can see what you've done in addition to your profile/CV so they don't have to do more work.
3. customize your CV to the job descriptions. Instead of letting the recruiter do the work to link what you did to the job requirements themselves, do that work for them in your customized CV and/or cover letter.
I've done all of the above and in reality looking for a job itself can be a full time job. Even if you're happy in your job you shouldn't stop networking (to enhance #1) and contributing on LinkedIn.
All the best.
Problem is some HR go along the racial lines and favoritism this is where ive seen HR push candidates who are ok on paper but concurrently reject some people who have potential as they are not of the preferred ethnicity, no specific ethnic group to blame as this trend is observed at some MnC or financial institutions as well. I had a friend who was a recruiter and told a certain Singaporean bank only wanted a specific ethnic group to be considered for the role which doesnt require any other language besides English and Bahasa so these cases I understand it isnt HR fault but the problem is when HR themselves have this bias the company loses a candidate who can contribute accordingly and the job seeker loses the opportunity to secure employment on their merit as this would give them a platform to develop. As much as US has a lot of flaws when it comes to employment i believe the west allows more diversity and appreciates talent more then Asian countries.
