I don't have a solid proof that it's a scam, but it looked like all the recruiter needed was my email and phone number - to sell it to some company running a scam. I received that scam call the very next morning. A woman with heavy Hindu accent who knew my name (scammer usually don't) was trying to "represent" some official research company (at 8am in the morning - researchers never do that), trying to skip the name of the company and get my consent to ask me some personal questions. I insisted on giving me full details about the research, and a full company name (not a fast spelled abbreviation), which she failed to do. I refused to answer any questions. That's it. The recruited disappeared. Didn't call at the scheduled time. Didn't follow up on LinkedIn, like if the conversation has never started. A few things that seemed like a "red flag" from the very beginning: - the job title didn't make sense. It was sounding "too good" for my LinkedIn profile. - in the details they sent via email, the job title was different! Close, but made event less sense. The details looked like a template that they could apply to different positions slightly adjusting the title. - some of the job didn't make sense, like if they were added by a person who knows nothing about the role - the tone and the phrasing was unusual for a recruiter. More aggressive, less formal. (But this can be personal, hard to rely on that) After receiving that unusual scam call I researched Collabera further and found that a couple scam alerts on Reddit, stating that on the interview they were requesting Social Security Number and other personal information. (Glad that I didn't get there!)
