Geneva Trading Software Developer interview questions

Firstly, someone from the HR department talks to you on the phone regarding your resume and application, in general. Then, an interview with an engineer at the company (which is pretty difficult). Then, they call you on-site.

The first round was an online test in c#...Well after which i received no input as to whether i was accepted or rejected After following up for quite sometime, I was called in for the next round.And for some reason they told me they had some technical difficulties and said they would schedule it some other time.Despite following up ,I received no reply at all.
