It's just an ordinary recruitment agency, nothing special.

Basically, I don't think there's any need to waste time going to the company for an interview; a phone interview would be enough—you have the skills to back it up. Once they recommend you to a company, you'll have an opportunity to interview, so there's really no need to go to Infront and interview with a consultant. It's basically a waste of everyone's time. Also, recruitment agencies will randomly recommend job openings. If they don't have any positions you want or that suit you, they basically just ignore you afterward.
