Initially i got a mail from the recruiter that the interview would we on Linux and Information security. The interview process was fast enough and they were communicating well. But the problem is that whatever topics they have mentioned in the job description was not asked by them. They were interested to know that whether I have knowledge on coding. My suggestion is that what ever position you apply in this company even it may be in administration or networking you need have good knowledge on one programming language, I mean they expect this.
