If you're wondering why you aren't being called for interviews even though you have the perfect CV, it could be because of these 4 websites.

In case you don’t already know, recruiters and hiring managers will Google you before inviting you for an interview. If what they find online contradicts what is presented on your CV, they'll throw it in the bin. However, if what they find about you online enhances your professional reputation, your chances of getting hired increases immensely.

So which websites are likely to help your job hunt? These three:

1. Who’s Who of Southern Africa

This local reputation management site allows you to put your best foot forward once you've created a profile. Not only is it one of the few websites that gets you onto Google’s first search result page, but it does so by highlighting your best achievements. The platform is the perfect way to display all the projects you’ve worked on, your previous employment, the companies you’re associated with, and if you’ve been featured in the news, it shows that too – and immediately rewards you for it.

It’s no secret that most people are lazy readers and to counter this Who’s Who SA has developed a badge and ranking system that rewards for your professional success. When hiring managers see how many badges you’ve earned, you’ve already impressed them.

2. LinkedIn

This international platform allows you to connect with other professionals around the world. It has made global networking easy. You’re able to join communities of people that share your interests and you can discuss the latest developments in your industry and share ideas.

Need an ‘in’ at a South African bank? Search Linkedin’s database and ‘Add’ it’s hiring manager, it’s head of department, and your future co-workers to your network.

It’s premium features allow you to contact anyone on the platform - from that recruiter who just viewed your profile to the hiring manager who's interested in you.

3. Careers24

South Africa’s leading job portal has thousands of vacancies available, posted by hundreds of recruiters. Once you’ve created a profile, applying for jobs is literally one click away. The platform also enables you to sign up so you can get jobs emailed to you directly. If you opt in, recruiters could even find you without you ever applying! Nothing is easier.

So which website is likely to harm your job hunt?

4. Facebook

Remember when it was said that hiring managers definitely Google you? This is one place you may not want them to see. If you haven’t already taken advantage of the privacy settings that Facebook offers, it may be the reason why you haven’t had any call-backs yet.

You may think you’re awesome because you have a million friends, have regular parties with them, and can afford the most expensive drinks, but your next boss is not impressed. In fact, he is the opposite.

No company wants to be associated with unprofessional behaviour or conflict magnets so stay away from posting rowdy pictures, embarrassing personal issues and controversial opinions and arguments. Always keep it professional.
