its basic question about coding and others like SQL query, C# fundamentals, work experience in previous company and etc. to be honest, its quite easy to join CCN but believe me u will challaged when you join this company.

I applied online. The process took quite fast (<1 Weeks). I interviewed a few months ago. Personally doesn't to like the answer that given by interviewer regarding internal advancement on career path, and I think the company culture doesn't fit for Z Generation People like me.
