At Forter (www.Forter.com) a big part is the screening of CVs. HR and RnD work closely to contact only relevant candidates, and when we a CV could be relevant the RnD manager or the lead developer calls the candidate for 15 minutes focusing on a key strength that makes the candidate relevant and why working at Forter is so great. The first interview is about the candidate's comfort zone. You would be amazed how many people don't know what they were working on about the past few years... plus a hands on algorithmic coding task that does not require experience (we hire also coders before college). The rest of the process (usually three more interviews) are mixed. Include technical, personal discussion. We try to fit all interviews into one day. Even though Israel is small and travel is non issue , there is a strong psychological effect if the candidate gets an offer after one visit. This might require in some cases talking with the candidates recommenders while she is interviewed in the next room.
