UST interview questions

They had informed in email that selection process consists of 3 rounds and if selected, immediate joining is required. I cleared all the 3 rounds. But after the process, they are saying that we have to undergo another technical evaluation after 2 or 3 months for which they have prescribed a curriculum. The syllabus of the curriculum is too tough for personal study and they have directed to undergo a course at a private institute paying Rs.60000. No other company does this. All reputed companies hire freshers and even provide them training free of cost. And here, we are directed to pay for getting the job which is not even an affordable amount.
