To identify data robbers and fake recruiters in the Indian job market, and to decide who should post their CV on LinkedIn, Naukri, and Indeed, here is a consolidated expert guide:

Identifying Data Robbers in Job Market India

Data robbers commonly infiltrate job portals using attacks like SQL injection and cross-site scripting to steal personal data such as names, phone numbers, emails, employment history, and more.
Be cautious of data theft scams involving unregistered companies or unofficial setups operating as recruitment agents or BPOs illegally selling personal data.
Large-scale data theft incidents have involved millions of job seekers’ data being stolen from multiple sites, so only post your CV on well-known, secure, and reputed platforms.

Some key warning signs of fake recruiters or job consultancy:

No in-person interview despite job offers.
Vague job descriptions or unclear role responsibilities.
Unprofessional communication full of grammar mistakes.
Suspicious or missing official contact details.
Asking for payment of registration, application, or processing fees before employment.
Recruiter hiding the company name or providing unverifiable details.
Requests for excessive personal or financial information (bank details, ID numbers) prematurely.

Verify recruiter and company authenticity by:

Confirming company registration through government or official registries.
Contacting company HR directly if recruiter claims to represent them.
Checking employee reviews and company presence on Glassdoor, LinkedIn, or other credible sources.

Freshers and entry-level candidates: Naukri is highly popular for entry and mid-level jobs with a wide local reach and many job listings. It is suitable for freshers to upload their CV and use keyword optimization to get visibility.
Experienced and career-focused professionals: LinkedIn is preferable for building a professional brand, networking, and long-term career growth. It helps create visibility and attracts recruiters beyond job boards.
Passive job seekers or those switching industries/international opportunities: Indeed combined with LinkedIn offers a good chance for broad job searching and employer reviews.
Keep profiles and resumes updated with relevant keywords, skills, and experience to improve chances on any platform.

Avoid posting your CV on untrusted or obscure sites; prefer reputed portals like Naukri, LinkedIn, and Indeed.
Watch for signs of fake recruiters such as fee demands, vague info, lack of company verification, and requests for excessive personal data.
Freshers may benefit from Naukri’s volume of listings; experienced workers should focus on LinkedIn for professional branding; Indeed is good for passive and international job hunting.
Always verify recruiters and companies independently and be cautious with your personal data to avoid data robbers.
