How do you interrogate people?

[The Stranger]

I approach them from behind and press RT (XBOX Controller) but I either end up knocking them out or they see me before I have the chance.

How do I hold them to interrogate them?

Sneak up on them (tilt the stick slightly to go slower so they don't hear you), then press and hold RT to grab them. While holding RT press and Hold RB (or is it LB, ? Pretty sure there is a promt) to open a menu and pick interrogate.

While you press the grab button, don't move the stick.

This seems to be what happens to you, since you say you knock them out most times.
(Grab+Stick Tilt=KO)

Just grab and hold the button until the enemy is in the chokehold.

And yerah, it's LB on XBone controller to start interrogating (also OP: Keep the grab button held down while doing whatever to your victim)

Edit: You can also aim at their head from behind (or the sides, as long as they don't see you), and then sneak up. They will surrender when they turn around and see you targeting their face.
Careful though, if you don't keep that aim, the enemy might try to grab a gun and shoot.

In this situation, you can also interrogate them, among other stuff.

You can also knock them out, kick them, point a weapon at them and then interrogate them. Only works if you haven't triggered an alarm though.

That is what I am doing.
They don't see / hear me, I hold RT for CQC but I don't grab them?
It's so weird, the only way to get the blueprint is to interrogate.

That's strange. As SiriuS pointed out you need to have the stick in neutral position when you press it. Maybe that's it?

Have you tried with keyboard controls to see if it's an issue with your controller?

Doesn't work on Keyboard either.
And I am literally just standing behind them, not moving, and then I hold RT.
I just hit him, even though I am still holding the trigger.

Last thing I can think off is you not being close enough. There should be a promt if you are. Maybe try crouching first. I don't think it matters, but it's been a while since I last played.

If it really doesn't work you can use the gun point methods described above. Sucks that you will have to go without one of the most effective takedowns though.

Yeah, there coems that RT and hand sign thing when I am close enough.
I am verifying my game files atm, see if that works. :(
