Interview is very easy, but in many steps, first HR calls you, ask some usual hr question. If he/she satisfied, then you will have inside interview with teamlead of project you'll work, technical interview, and if they like you too, hr will call you to discuss the salery and other thing ... each step will be about 2 weeks, so if you send a CV a they didn't call you 3 weeks, forget about this companie :)
