From my experience, yes it is fake+Scam . But there are other accounts on the internet swearing by e-litmus and amcat. I've taken both(and earned high percentiles in each) and asides from really horrible, slavery-tier "training" jobs, I've yet to hear from or even see the mention of a big company.
And when I mean slavery tier, I'm talking about salaries between Rs. 8000 and Rs. 13000 per month type jobs with 12 hour work shifts and officials telling me that the candidate must be willing to put in "all hours of the day". The moment I heard that followed by what they called "salary", I told him to put his Rs. 8000 you-know-where.
These are the type of calls you can expect from companies associated with eLitmus and amcat. I also get a feeling that both eLitmus and amcat employees post fake reviews online on top google search results for their respective pages. This is from the generally broken half-worded and nonsensical gibberish what passes for them as English with which they try (but end up sounding idiotic) to imply that a candidate was given a top-job at Accenture, HCL etc. They're crooks. Stay away and apply online and through contacts.
So if you have 5LPA salary you should not at all waste your money in these scams and try other ways if you want a higher package then you currently have!!!
