I applied through a staffing agency. The process took 3 weeks. I interviewed at Exponential-e (London, England) in Mar 2016
Interview
The process was fairly quick once I got past the interview. I was meant to have the interview on the Thursday, which was moved 2 times, to Friday, then Monday. Once inside, I came in and the interviewer was around 10 minutes late, and the interview went on for around an hour and half.
After the interview was finished, I went home about 3 hours later they called me and told me I start in 2 weeks if I accept.
I applied through a recruiter. The process took 1 week. I interviewed at Exponential-e (London, England)
Interview
Phone and face to face interview. Questions were at CCNA level. Make sure you know the layer 2 basics very well and also OSPF. Make sure you understand how a switch learns a mac address, how vlans work and how trunking works. It is probably a good idea to have a good understanding of Default Gateway high availability and Some prior knowledge of BGP and VPN will definitely work in your favour.
