Heard of Convin AI?

Not a good company.i agree with @Tattiman here

If you can see red flags, trust your gut and don’t proceed forward.

One thing which really bothered me when I checked the company on linkedin was most of the emp were interns and their majority workforce is sales not engineering so it's going to be a sales driven org.
Most employee as intent would indicate they just wanted to get things done for cheap and were not looking to pay. Even the guy who called me was hr intern and had no idea when I asked a question. These were few red flags I found .
