I applied online. The process took 5 days. I interviewed at MDS Technology (Crawley, West Sussex, South East England, England) in Mar 2012
Interview
Fairly straightforward, must've been under 20 questions.
Some networking questions (netmasks, broadcast, general subnetting), some Windows questions (services, scheduled jobs, IIS), some hardware questions (RAID array types, hotswap, redundant PSUs, even some electricity-related questions!) .
Not a challenging interview, they were happy to get an employee around there and I was happy to get a job.
