Israeli made series, follows a training cohort into the one of the most elite and famous intel agencies in the world

If you read and liked By Way of Deception, there's some elements of that featured

Premise is Mossad officer Yona is brought back to HQ after botching an operation in Bulgaria.
For some reason he's given a "desk job" of training the next batch of recruits

It's set up like Survivor, every ep features some mission impossible task for the recruits and at the end one of them is kicked out for failing in some aspect

The recruits are Israelis from all over the world: Russia, USA, Brazil, France, even an Iranian dude. They bring in their cultural prism and faults and virtues.

Yona is also obsessed with Abigail, his ex wife. Trying to get her back but goes about it on some stalker shit. She's also a Mossad psychologist so hilarity ensues

3 eps in so far, it avoids the after school special feel of Quantico and it's not up its own ass like Homeland (gotta find the original Israeli version).
