I was with a tour group (12 people) last month and flew out of TLV on KL. The group leader and one other member got questioned. Their interviews took roughly 10-15 minutes, I guess. They kept the rest of us in line, but then we each had a short (about 30-45 seconds) "interview" concerning the group, how we belonged to the group, and about our carry-ons. I'm positive they were just verifying the answers matched.

Then all your checked luggage gets put through an xray machine where it is scanned from different angles. After it is scanned, you either get sent directly to the airline check-in desk or get sent to another station to explain anything suspicious seen from the xray images.

Then after check-in, your next stop is the WTMD. Shoes stayed on. Laptops came out. I didn't alarm so I didn't stick around to see what happens when someone does.

Once past the WTMD, it was a long walk to the gates, but there was nothing else security-wise to worry about. No gate searches at all.
