This is the future of immigration imho. In coming years, this will also be screened as well. In my uni - I have been telling everyone to not use any agents to book a slot rather try on their.
Now let me tell how it works - if you track your CEAC portal, they open your case 2-3 days before your interview and check everything to see your social media, IP addresses or anything unusual and they mark it. Some considerate VO may ignore your weaknesses if your appearance & confidence is there. But in future I think they will mandate the policy of not taking help of agents. I think this system has got broken because of Agents & they should blacklist all the agents & charge them. Most of the people in my uni are not able to get a slot - this is because many agents are rigging the system on daily basis. On top of it India IT community in USA have been habitual offenders of migration policy, finding loopholes, h1b frauds.
If you want a Visa in future time be honest, full your ds160 on your own, book your own slot and get into a reputed uni.
