Emtek Engineering Graduate Engineering Trainee GET interview questions

Its a fake company with fake job profiles for freshers. I don't know how they reached me, because I have never applied in this company (may be from job search websites). Since ,I was looking for a job in my core engineering field so I went there. The interview process is normal and similar to most of the other companies. It includes 3 rounds followed by: 1. Aptitude test for 15 min. 2. Technical Interview 10 min. 3. HR round 10 min. After the completion of your interview, the HR manager will send a mail for your pre-selection round by the end of the day, in which they demand for unnecessary security amount along with six month bond claiming it as a policy of the company (this was not told to me earlier at the time of interview). One thing I understood about this company is, it is just an unauthorized firm that has open a business of employment and making fool out of all the unemployed and helpless graduates who are looking for an opportunity to work in a core field.
